Chris Anderson: Hello.
Welcome to this TED Dialogue.
-
It's the first of a series
that's going to be done
-
in response to the current
political upheaval.
-
I don't know about you;
-
I've become quite concerned about
the growing divisiveness in this country
-
and in the world.
-
No one's listening to each other. Right?
-
They aren't.
-
I mean, it feels like we need
a different kind of conversation,
-
one that's based on -- I don't know,
on reason, listening, on understanding,
-
on a broader context.
-
That's at least what we're going to try
in these TED Dialogues,
-
starting today.
-
And we couldn't have anyone with us
-
who I'd be more excited to kick this off.
-
This is a mind right here that thinks
pretty much like no one else
-
on the planet, I would hasten to say.
-
I'm serious.
-
(Yuval Noah Harari laughs)
-
I'm serious.
-
He synthesizes history
with underlying ideas
-
in a way that kind of takes
your breath away.
-
So, some of you will know
this book, "Sapiens."
-
Has anyone here read "Sapiens"?
-
(Applause)
-
I mean, I could not put it down.
-
The way that he tells the story of mankind
-
through big ideas that really make you
think differently --
-
it's kind of amazing.
-
And here's the follow-up,
-
which I think is being published
in the US next week.
-
YNH: Yeah, next week.
-
CA: "Homo Deus."
-
Now, this is the history
of the next hundred years.
-
I've had a chance to read it.
-
It's extremely dramatic,
-
and I daresay, for some people,
quite alarming.
-
It's a must-read.
-
And honestly, we couldn't have
someone better to help
-
make sense of what on Earth
is happening in the world right now.
-
So a warm welcome, please,
to Yuval Noah Harari.
-
(Applause)
-
It's great to be joined by our friends
on Facebook and around the Web.
-
Hello, Facebook.
-
And all of you, as I start
asking questions of Yuval,
-
come up with your own questions,
-
and not necessarily about
the political scandal Du jour,
-
but about the broader understanding
of: Where are we heading?
-
You ready? OK, we're going to go.
-
So here we are, Yuval:
-
New York City, 2017,
there's a new president in power,
-
and shock waves rippling around the world.
-
What on Earth is happening?
-
YNH: I think the basic thing that happened
-
is that we have lost our story.
-
Humans think in stories,
-
and we try to make sense of the world
by telling stories.
-
And for the last few decades,
-
we had a very simple
and very attractive story
-
about what's happening in the world.
-
And the story said that,
oh, what's happening is
-
that the economy is being globalized,
-
politics is being liberalized,
-
and the combination of the two
will create paradise on Earth,
-
and we just need to keep on
globalizing the economy
-
and liberalizing the political system,
-
and everything will be wonderful.
-
And 2016 is the moment
-
when a very large segment,
even of the Western world,
-
stopped believing in this story.
-
For good or bad reasons --
it doesn't matter.
-
People stopped believing in the story,
-
and when you don't have a story,
you don't understand what's happening.
-
CA: Part of you believes that that story
was actually a very effective story.
-
It worked.
-
YNH: To some extent, yes.
-
According to some measurements,
-
we are now in the best time ever
-
for humankind.
-
Today, for the first time in history,
-
more people die from eating too much
than from eating too little,
-
which is an amazing achievement.
-
(Laughter)
-
Also for the first time in history,
-
more people die from old age
than from infectious diseases,
-
and violence is also down.
-
For the first time in history,
-
more people commit suicide
than are killed by crime and terrorism
-
and war put together.
-
Statistically, you are
your own worst enemy.
-
At least, of all the people in the world,
-
you are most likely
to be killed by yourself --
-
(Laughter)
-
which is, again,
very good news, compared --
-
(Laughter)
-
compared to the level of violence
that we saw in previous eras.
-
CA: But this process
of connecting the world
-
ended up with a large group of people
kind of feeling left out,
-
and they've reacted.
-
And so we have this bombshell
-
that's sort of ripping
through the whole system.
-
I mean, what do you make
of what's happened?
-
It feels like the old way
that people thought of politics,
-
the left-right divide,
has been blown up and replaced.
-
How should we think of this?
-
YNH: Yeah, the old 20th-century
political model of left versus right
-
is now largely irrelevant,
-
and the real divide today
is between global and national,
-
global or local.
-
And you see it again all over the world
-
that this is now the main struggle.
-
We probably need completely
new political models
-
and completely new ways
of thinking about politics.
-
In essence, what you can say
is that we now have global ecology,
-
we have a global economy
but we have national politics,
-
and this doesn't work together.
-
This makes the political
system ineffective,
-
because it has no control
over the forces that shape our life.
-
And you have basically two solutions
to this imbalance:
-
either de-globalize the economy
and turn it back into a national economy,
-
or globalize the political system.
-
CA: So some, I guess
many, liberals out there
-
view Trump and his government
as kind of irredeemably bad,
-
just awful in every way.
-
Do you see any underlying narrative
or political philosophy in there
-
that is at least worth understanding?
-
How would you articulate that philosophy?
-
Is it just the philosophy of nationalism?
-
YNH: I think the underlying
feeling or idea
-
is that the political system --
something is broken there.
-
It doesn't empower
the ordinary person anymore.
-
It doesn't care so much
about the ordinary person anymore,
-
and I think this diagnosis
of the political disease is correct.
-
With regard to the answers,
I am far less certain.
-
I think what we are seeing
is the immediate human reaction:
-
if something doesn't work, let's go back.
-
And you see it all over the world,
-
that people, almost nobody
in the political system today,
-
has any future-oriented vision
of where humankind is going.
-
Almost everywhere,
you see retrograde vision:
-
"Let's make America great again,"
-
like it was great -- I don't know --
in the '50s, in the '80s, sometime,
-
let's go back there.
-
And you go to Russia
a hundred years after Lenin,
-
Putin's vision for the future
-
is basically, ah, let's go back
to the Tsarist empire.
-
And in Israel, where I come from,
-
the hottest political vision
of the present is:
-
"Let's build the temple again."
-
So let's go back 2,000 years backwards.
-
So people are thinking
sometime in the past we've lost it,
-
and sometimes in the past, it's like
you've lost your way in the city,
-
and you say OK, let's go back
to the point where I felt secure
-
and start again.
-
I don't think this can work,
-
but a lot of people,
this is their gut instinct.
-
CA: But why couldn't it work?
-
"America First" is a very
appealing slogan in many ways.
-
Patriotism is, in many ways,
a very noble thing.
-
It's played a role
in promoting cooperation
-
among large numbers of people.
-
Why couldn't you have a world
organized in countries,
-
all of which put themselves first?
-
YNH: For many centuries,
even thousands of years,
-
patriotism worked quite well.
-
Of course, it led to wars an so forth,
-
but we shouldn't focus
too much on the bad.
-
There are also many,
many positive things about patriotism,
-
and the ability to have
a large number of people
-
care about each other,
-
sympathize with one another,
-
and come together for collective action.
-
If you go back to the first nations,
-
so, thousands of years ago,
-
the people who lived along
the Yellow River in China --
-
it was many, many different tribes
-
and they all depended on the river
for survival and for prosperity,
-
but all of them also suffered
from periodical floods
-
and periodical droughts.
-
And no tribe could really do
anything about it,
-
because each of them controlled
just a tiny section of the river.
-
And then in a long
and complicated process,
-
the tribes coalesced together
to form the Chinese nation,
-
which controlled the entire Yellow River
-
and had the ability to bring
hundreds of thousands of people together
-
to build dams and canals
and regulate the river
-
and prevent the worst floods and droughts
-
and raise the level
of prosperity for everybody.
-
And this worked in many places
around the world.
-
But in the 21st century,
-
technology is changing all that
in a fundamental way.
-
We are now living -- all people
in the world --
-
are living alongside the same cyber river,
-
and no single nation can regulate
this river by itself.
-
We are all living together
on a single planet,
-
which is threatened by our own actions,
-
and if you don't have some kind
of global cooperation,
-
nationalism is just not on the right level
to tackle the problems,
-
whether it's climate change
or whether it's technological disruption.
-
CA: So it was a beautiful idea
-
in a world where most of the action,
most of the issues,
-
took place on national scale,
-
but your argument is that the issues
that matter most today
-
no longer take place on a national scale
but on a global scale.
-
YNH: Exactly. All the major problems
of the world today
-
are global in essence,
-
and they cannot be solved
-
unless through some kind
of global cooperation.
-
It's not just climate change,
-
which is, like, the most obvious
example people give.
-
I think more in terms
of technological disruption.
-
If you think about, for example,
artificial intelligence,
-
over the next 20, 30 years
-
pushing hundreds of millions of people
out of the job market --
-
this is a problem on a global level.
-
It will disrupt the economy
of all the countries.
-
And similarly, if you think
about, say, bioengineering
-
and people being afraid of conducting,
-
I don't know, genetic engineering
research in humans,
-
it won't help if just
a single country, let's say the US,
-
outlaws all genetic experiments in humans,
-
but China or North Korea
continues to do it.
-
So the US cannot solve it by itself,
-
and very quickly, the pressure on the US
to do the same will be immense
-
because we are talking about
high-risk, high-gain technologies.
-
If somebody else is doing it,
I can't allow myself to remain behind.
-
The only way to have regulations,
effective regulations,
-
on things like genetic engineering,
-
is to have global regulations.
-
If you just have national regulations,
nobody would like to stay behind.
-
CA: So this is really interesting.
-
It seems to me that this may be one key
-
to provoking at least
a constructive conversation
-
between the different sides here,
-
because I think everyone can agree
that the start point
-
of a lot of the anger
that's propelled us to where we are
-
is because of the legitimate
concerns about job loss.
-
Work is gone, a traditional
way of life has gone,
-
and it's no wonder
that people are furious about that.
-
And in general, they have blamed
globalism, global elites,
-
for doing this to them
without asking their permission,
-
and that seems like
a legitimate complaint.
-
But what I hear you saying
is that -- so a key question is:
-
What is the real cause of job loss,
both now and going forward?
-
To the extent that it's about globalism,
-
then the right response,
yes, is to shut down borders
-
and keep people out
and change trade agreements and so forth.
-
But you're saying, I think,
-
that actually the bigger cause of job loss
is not going to be that at all.
-
It's going to originate
in technological questions,
-
and we have no chance of solving that
-
unless we operate as a connected world.
-
YNH: Yeah, I think that,
-
I don't know about the present,
but looking to the future,
-
it's not the Mexicans or Chinese
who will take the jobs
-
from the people in Pennsylvania,
-
it's the robots and algorithms.
-
So unless you plan to build a big wall
on the border of California --
-
(Laughter)
-
the wall on the border with Mexico
is going to be very ineffective.
-
And I was struck when I watched
the debates before the election,
-
I was struck that certainly Trump
did not even attempt to frighten people
-
by saying the robots will take your jobs.
-
Now even if it's not true,
it doesn't matter.
-
It could have been an extremely
effective way of frightening people --
-
(Laughter)
-
and galvanizing people:
-
"The robots will take your jobs!"
-
And nobody used that line.
-
And it made me afraid,
-
because it meant
that no matter what happens
-
in universities and laboratories,
-
and there, there is already
an intense debate about it,
-
but in the mainstream political system
and among the general public,
-
people are just unaware
-
that there could be an immense
technological disruption --
-
not in 200 years,
but in 10, 20, 30 years --
-
and we have to do something about it now,
-
partly because most of what we teach
children today in school or in college
-
is going to be completely irrelevant
to the job market of 2040, 2050.
-
So it's not something we'll need
to think about in 2040.
-
We need to think today
what to teach the young people.
-
CA: Yeah, no, absolutely.
-
You've often written about
moments in history
-
where humankind has ...
entered a new era, unintentionally.
-
Decisions have been made,
technologies have been developed,
-
and suddenly the world has changed,
-
possibly in a way
that's worse for everyone.
-
So one of the examples
you give in "Sapiens"
-
is just the whole agricultural revolution,
-
which, for an actual person
tilling the fields,
-
they just picked up a 12-hour
backbreaking workday
-
instead of six hours in the jungle
and a much more interesting lifestyle.
-
(Laughter)
-
So are we at another possible
phase change here,
-
where we kind of sleepwalk into a future
that none of us actually wants?
-
YNH: Yes, very much so.
-
During the agricultural revolution,
-
what happened is that immense
technological and economic revolution
-
empowered the human collective,
-
but when you look at actual
individual lives,
-
the life of a tiny elite
became much better,
-
and the lives of the majority of people
became considerably worse.
-
And this can happen again
in the 21st century.
-
No doubt the new technologies
will empower the human collective.
-
But we may end up again
-
with a tiny elite reaping
all the benefits, taking all the fruits,
-
and the masses of the population
finding themselves worse
-
than they were before,
-
certainly much worse than this tiny elite.
-
CA: And those elites
might not even be human elites.
-
They might be cyborgs or --
-
YNH: Yeah, they could be
enhanced super humans.
-
They could be cyborgs.
-
They could be completely
nonorganic elites.
-
They could even be
non-conscious algorithms.
-
What we see now in the world
is authority shifting away
-
from humans to algorithms.
-
More and more decisions --
about personal lives,
-
about economic matters,
about political matters --
-
are actually being taken by algorithms.
-
If you ask the bank for a loan,
-
chances are your fate is decided
by an algorithm, not by a human being.
-
And the general impression
is that maybe Homo sapiens just lost it.
-
The world is so complicated,
there is so much data,
-
things are changing so fast,
-
that this thing that evolved
on the African savanna
-
tens of thousands of years ago --
-
to cope with a particular environment,
-
a particular volume
of information and data --
-
it just can't handle the realities
of the 21st century,
-
and the only thing
that may be able to handle it
-
is big-data algorithms.
-
So no wonder more and more authority
is shifting from us to the algorithms.
-
CA: So we're in New York City
for the first of a series of TED Dialogues
-
with Yuval Harari,
-
and there's a Facebook Live
audience out there.
-
We're excited to have you with us.
-
We'll start coming
to some of your questions
-
and questions of people in the room
-
in just a few minutes,
-
so have those coming.
-
Yuval, if you're going
to make the argument
-
that we need to get past nationalism
because of the coming technological ...
-
danger, in a way,
-
presented by so much of what's happening
-
we've got to have
a global conversation about this.
-
Trouble is, it's hard to get people
really believing that, I don't know,
-
AI really is an imminent
threat, and so forth.
-
The things that people,
some people at least,
-
care about much more immediately, perhaps,
-
is climate change,
-
perhaps other issues like refugees,
nuclear weapons, and so forth.
-
Would you argue that where
we are right now
-
that somehow those issues
need to be dialed up?
-
You've talked about climate change,
-
but Trump has said
he doesn't believe in that.
-
So in a way, your most powerful argument,
-
you can't actually use to make this case.
-
YNH: Yeah, I think with climate change,
-
at first sight, it's quite surprising
-
that there is a very close correlation
-
between nationalism and climate change.
-
I mean, almost always, the people
who deny climate change are nationalists.
-
And at first sight, you think: Why?
-
What's the connection?
-
Why don't you have socialists
denying climate change?
-
But then, when you think
about it, it's obvious --
-
because nationalism has no solution
to climate change.
-
If you want to be a nationalist
in the 21st century,
-
you have to deny the problem.
-
If you accept the reality of the problem,
then you must accept that, yes,
-
there is still room in the world
for patriotism,
-
there is still room in the world
for having special loyalties
-
and obligations towards your own people,
towards your own country.
-
I don't think anybody is really
thinking of abolishing that.
-
But in order to confront climate change,
-
we need additional loyalties
and commitments
-
to a level beyond the nation.
-
And that should not be impossible,
-
because people can have
several layers of loyalty.
-
You can be loyal to your family
-
and to your community
-
and to your nation,
-
so why can't you also be loyal
to humankind as a whole?
-
Of course, there are occasions
when it becomes difficult,
-
what to put first,
-
but, you know, life is difficult.
-
Handle it.
-
(Laughter)
-
CA: OK, so I would love to get
some questions from the audience here.
-
We've got a microphone here.
-
Speak into it, and Facebook,
get them coming, too.
-
Question: One of the things that has
clearly made a huge difference
-
in this country and other countries
-
is the income distribution inequality,
-
the dramatic change
in income distribution in the US
-
from what it was 50 years ago,
-
and around the world.
-
Is there anything we can do
to affect that?
-
Because that gets at a lot
of the underlying causes.
-
YNH: So far I haven't heard a very
good idea about what to do about it,
-
again, partly because most ideas
remain on the national level,
-
and the problem is global.
-
I mean, one idea that we hear
quite a lot about now
-
is universal basic income.
-
But this is a problem.
-
I mean, I think it's a good start,
-
but it's a problematic idea because
it's not clear what "universal" is
-
and it's not clear what "basic" is.
-
Most people when they speak
about universal basic income,
-
they actually mean national basic income.
-
But the problem is global.
-
Let's say that you have AI and 3D printers
taking away millions of jobs
-
in Bangladesh,
-
from all the people who make
my shirts and my shoes.
-
So what's going to happen?
-
The US government will levy taxes
on Google and Apple in California,
-
and use that to pay basic income
to unemployed Bangladeshis?
-
If you believe that,
you can just as well believe
-
that Santa Claus will come
and solve the problem.
-
So unless we have really universal
and not national basic income,
-
the deep problems
are not going to go away.
-
And also it's not clear what basic is,
-
because what are basic human needs?
-
A thousand years ago,
just food and shelter was enough.
-
But today, people will say
education is a basic human need,
-
it should be part of the package.
-
But how much? Six years?
Twelve years? PhD?
-
Similarly, with health care,
-
let's say that in 20, 30, 40 years,
-
you'll have expensive treatments
that can extend human life
-
to 120, I don't know.
-
Will this be part of the basket
of basic income or not?
-
It's a very difficult problem,
-
because in a world where people
lose their ability to be employed,
-
the only thing they are going to get
is this basic income.
-
So what's part of it is a very,
very difficult ethical question.
-
CA: There's a bunch of questions
on how the world affords it as well,
-
who pays.
-
There's a question here
from Facebook from Lisa Larson:
-
"How does nationalism in the US now
-
compare to that between
World War I and World War II
-
in the last century?"
-
YNH: Well the good news, with regard
to the dangers of nationalism,
-
we are in a much better position
than a century ago.
-
A century ago, 1917,
-
Europeans were killing
each other by the millions.
-
In 2016, with Brexit,
as far as I remember,
-
a single person lost their life,
an MP who was murdered by some extremist.
-
Just a single person.
-
I mean, if Brexit was about
British independence,
-
this is the most peaceful
war of independence in human history.
-
And let's say that Scotland
will now choose to leave the UK
-
after Brexit.
-
So in the 18th century,
-
if Scotland wanted -- and the Scots
wanted several times --
-
to break out of the control of London,
-
the reaction of the government
in London was to send an army up north
-
to burn down Edinburgh
and massacre the highland tribes.
-
My guess is that if, in 2018,
the Scots vote for independence,
-
the London government
will not send an army up north
-
to burn down Edinburgh.
-
Very few people are now willing
to kill or be killed
-
for Scottish or for British independence.
-
So for all the talk
of the rise of nationalism
-
and going back to the 1930s,
-
to the 19th century, in the West at least,
-
the power of national sentiments
today is far, far smaller
-
than it was a century ago.
-
CA: Although some people now,
you hear publicly worrying
-
about whether that might be shifting,
-
that there could actually be
outbreaks of violence in the US
-
depending on how things turn out.
-
Should we be worried about that,
-
or do you really think
things have shifted?
-
YNH: No, we should be worried.
-
We should be aware of two things.
-
First of all, don't be hysterical.
-
We are not back
in the First World War yet.
-
But on the other hand,
don't be complacent.
-
We reached from 1917 to 2017,
-
not by some divine miracle,
-
but simply by human decisions,
-
and if we now start making
the wrong decisions,
-
we could be back
in an analogous situation to 1917
-
in a few years.
-
One of the things I know as a historian
-
is that you should never
underestimate human stupidity.
-
(Laughter)
-
It's one of the most powerful
forces in history,
-
human stupidity and human violence.
-
Humans do such crazy things
for no obvious reason,
-
but again, at the same time,
-
another very powerful force
in human history is human wisdom.
-
We have both.
-
CA: We have with us here
moral psychologist Jonathan Haidt,
-
who I think has a question.
-
Jonathan Haidt: Thanks, Yuval.
-
So you seem to be a fan
of global governance,
-
but when you look at the map of the world
from Transparency International,
-
which rates the level of corruption
of political institutions,
-
it's a vast sea of red with little bits
of yellow here and there
-
for those with good institutions.
-
So if we were to have
some kind of global governance,
-
what makes you think it would end up
being more like Denmark
-
rather than more like Russia or Honduras,
-
and aren't there alternatives,
-
such as we did with CFCs?
-
There are ways to solve global problems
with national governments.
-
What would world government
actually look like,
-
and why do you think it would work?
-
YNH: Well, I don't know
what it would look like.
-
Nobody still has a model for that.
-
The main reason we need it
-
is because many of these issues
are lose-lose situations.
-
When you have
a win-win situation like trade,
-
both sides can benefit
from a trade agreement,
-
then this is something you can work out.
-
Without some kind of global government,
-
national governments each
have an interest in doing it.
-
But when you have a lose-lose situation
like with climate change,
-
it's much more difficult
-
without some overarching
authority, real authority.
-
Now, how to get there
and what would it look like,
-
I don't know.
-
And certainly there is no obvious reason
-
to think that it would look like Denmark,
-
or that it would be a democracy.
-
Most likely it wouldn't.
-
We don't have workable democratic models
-
for a global government.
-
So maybe it would look more
like ancient China
-
than like modern Denmark.
-
But still, given the dangers
that we are facing,
-
I think the imperative of having
some kind of real ability
-
to force through difficult decisions
on the global level
-
is more important
than almost anything else.
-
CA: There's a question from Facebook here,
-
and then we'll get the mic to Andrew.
-
So, Kat Hebron on Facebook,
-
calling in from Vail:
-
"How would developed nations manage
the millions of climate migrants?"
-
YNH: I don't know.
-
CA: That's your answer, Kat. (Laughter)
-
YNH: And I don't think
that they know either.
-
They'll just deny the problem, maybe.
-
CA: But immigration, generally,
is another example of a problem
-
that's very hard to solve
on a nation-by-nation basis.
-
One nation can shut its doors,
-
but maybe that stores up
problems for the future.
-
YNH: Yes, I mean --
it's another very good case,
-
especially because it's so much easier
-
to migrate today
-
than it was in the Middle Ages
or in ancient times.
-
CA: Yuval, there's a belief
among many technologists, certainly,
-
that political concerns
are kind of overblown,
-
that actually, political leaders
don't have that much influence
-
in the world,
-
that the real determination of humanity
at this point is by science,
-
by invention, by companies,
-
by many things
other than political leaders,
-
and it's actually very hard
for leaders to do much,
-
so we're actually worrying
about nothing here.
-
YNH: Well, first, it should be emphasized
-
that it's true that political leaders'
ability to do good is very limited,
-
but their ability to do harm is unlimited.
-
There is a basic imbalance here.
-
You can still press the button
and blow everybody up.
-
You have that kind of ability.
-
But if you want, for example,
to reduce inequality,
-
that's very, very difficult.
-
But to start a war,
-
you can still do so very easily.
-
So there is a built-in imbalance
in the political system today
-
which is very frustrating,
-
where you cannot do a lot of good
but you can still do a lot of harm.
-
And this makes the political system
still a very big concern.
-
CA: So as you look at
what's happening today,
-
and putting your historian's hat on,
-
do you look back in history at moments
when things were going just fine
-
and an individual leader really took
the world or their country backwards?
-
YNH: There are quite a few examples,
-
but I should emphasize,
it's never an individual leader.
-
I mean, somebody put him there,
-
and somebody allowed him
to continue to be there.
-
So it's never really just the fault
of a single individual.
-
There are a lot of people
behind every such individual.
-
CA: Can we have the microphone
here, please, to Andrew?
-
Andrew Solomon: You've talked a lot
about the global versus the national,
-
but increasingly, it seems to me,
-
the world situation
is in the hands of identity groups.
-
We look at people within the United States
-
who have been recruited by ISIS.
-
We look at these other groups
which have formed
-
which go outside of national bounds
-
but still represent
significant authorities.
-
How are they to be integrated
into the system,
-
and how is a diverse set of identities
to be made coherent
-
under either national
or global leadership?
-
YNH: Well, the problem
of such diverse identities
-
is a problem from nationalism as well.
-
Nationalism believes
in a single, monolithic identity,
-
and exclusive or at least
more extreme versions of nationalism
-
believe in an exclusive loyalty
to a single identity.
-
And therefore, nationalism has had
a lot of problems
-
with people wanting to divide
their identities
-
between various groups.
-
So it's not just a problem, say,
for a global vision.
-
And I think, again, history shows
-
that you shouldn't necessarily
think in such exclusive terms.
-
If you think that there is just
a single identity for a person,
-
"I am just X, that's it, I can't be
several things, I can be just that,"
-
that's the start of the problem.
-
You have religions, you have nations
-
that sometimes demand exclusive loyalty,
-
but it's not the only option.
-
There are many religions and many nations
-
that enable you to have
diverse identities at the same time.
-
CA: But is one explanation
of what's happened in the last year
-
that a group of people have got
fed up with, if you like,
-
the liberal elites,
for want of a better term,
-
obsessing over many, many different
identities and them feeling,
-
"But what about my identity?
I am being completely ignored here.
-
And by the way, I thought
I was the majority"?
-
And that that's actually
sparked a lot of the anger.
-
YNH: Yeah. Identity is always problematic,
-
because identity is always based
on fictional stories
-
that sooner or later collide with reality.
-
Almost all identities,
-
I mean, beyond the level
of the basic community
-
of a few dozen people,
-
are based on a fictional story.
-
They are not the truth.
-
They are not the reality.
-
It's just a story that people invent
and tell one another
-
and start believing.
-
And therefore all identities
are extremely unstable.
-
They are not a biological reality.
-
Sometimes nationalists, for example,
-
think that the nation
is a biological entity.
-
It's made of the combination
of soil and blood,
-
creates the nation.
-
But this is just a fictional story.
-
CA: Soil and blood
kind of makes a gooey mess.
-
(Laughter)
-
YNH: It does, and also
it messes with your mind
-
when you think too much
that I am a combination of soil and blood.
-
If you look from a biological perspective,
-
obviously none of the nations
that exist today
-
existed 5,000 years ago.
-
Homo sapiens is a social animal,
that's for sure.
-
But for millions of years,
-
Homo sapiens and our hominid ancestors
lived in small communities
-
of a few dozen individuals.
-
Everybody knew everybody else.
-
Whereas modern nations
are imagined communities,
-
in the sense that I don't even know
all these people.
-
I come from a relatively
small nation, Israel,
-
and of eight million Israelis,
-
I never met most of them.
-
I will never meet most of them.
-
They basically exist here.
-
CA: But in terms of this identity,
-
this group who feel left out
and perhaps have work taken away,
-
I mean, in "Homo Deus,"
-
you actually speak of this group
in one sense expanding,
-
that so many people
may have their jobs taken away
-
by technology in some way
that we could end up with
-
a really large -- I think you call it
a "useless class" --
-
a class where traditionally,
-
as viewed by the economy,
these people have no use.
-
YNH: Yes.
-
CA: How likely a possibility is that?
-
Is that something
we should be terrified about?
-
And can we address it in any way?
-
YNH: We should think about it
very carefully.
-
I mean, nobody really knows
what the job market will look like
-
in 2040, 2050.
-
There is a chance
many new jobs will appear,
-
but it's not certain.
-
And even if new jobs do appear,
-
it won't necessarily be easy
-
for a 50-year old unemployed truck driver
-
made unemployed by self-driving vehicles,
-
it won't be easy
for an unemployed truck driver
-
to reinvent himself or herself
as a designer of virtual worlds.
-
Previously, if you look at the trajectory
of the industrial revolution,
-
when machines replaced humans
in one type of work,
-
the solution usually came
from low-skill work
-
in new lines of business.
-
So you didn't need any more
agricultural workers,
-
so people moved to working
in low-skill industrial jobs,
-
and when this was taken away
by more and more machines,
-
people moved to low-skill service jobs.
-
Now, when people say there will
be new jobs in the future,
-
that humans can do better than AI,
-
that humans can do better than robots,
-
they usually think about high-skill jobs,
-
like software engineers
designing virtual worlds.
-
Now, I don't see how
an unemployed cashier from Wal-Mart
-
reinvents herself or himself at 50
as a designer of virtual worlds,
-
and certainly I don't see
-
how the millions of unemployed
Bangladeshi textile workers
-
will be able to do that.
-
I mean, if they are going to do it,
-
we need to start teaching
the Bangladeshis today
-
how to be software designers,
-
and we are not doing it.
-
So what will they do in 20 years?
-
CA: So it feels like you're really
highlighting a question
-
that's really been bugging me
the last few months more and more.
-
It's almost a hard question
to ask in public,
-
but if any mind has some wisdom
to offer in it, maybe it's yours,
-
so I'm going to ask you:
-
What are humans for?
-
YNH: As far as we know, for nothing.
-
(Laughter)
-
I mean, there is no great cosmic drama,
some great cosmic plan,
-
that we have a role to play in.
-
And we just need to discover
what our role is
-
and then play it to the best
of our ability.
-
This has been the story of all religions
and ideologies and so forth,
-
but as a scientist, the best I can say
is this is not true.
-
There is no universal drama
with a role in it for Homo sapiens.
-
So --
-
CA: I'm going to push back on you
just for a minute,
-
just from your own book,
-
because in "Homo Deus,"
-
you give really one of the most coherent
and understandable accounts
-
about sentience, about consciousness,
-
and that unique sort of human skill.
-
You point out that it's different
from intelligence,
-
the intelligence
that we're building in machines,
-
and that there's actually a lot
of mystery around it.
-
How can you be sure there's no purpose
-
when we don't even understand
what this sentience thing is?
-
I mean, in your own thinking,
isn't there a chance
-
that what humans are for
is to be the universe's sentient things,
-
to be the centers of joy and love
and happiness and hope?
-
And maybe we can build machines
that actually help amplify that,
-
even if they're not going to become
sentient themselves?
-
Is that crazy?
-
I kind of found myself hoping that,
reading your book.
-
YNH: Well, I certainly think that the most
interesting question today in science
-
is the question
of consciousness and the mind.
-
We are getting better and better
in understanding the brain
-
and intelligence,
-
but we are not getting much better
-
in understanding the mind
and consciousness.
-
People often confuse intelligence
and consciousness,
-
especially in places like Silicon Valley,
-
which is understandable,
because in humans, they go together.
-
I mean, intelligence basically
is the ability to solve problems.
-
Consciousness is the ability
to feel things,
-
to feel joy and sadness
and boredom and pain and so forth.
-
In Homo sapiens and all other mammals
as well -- it's not unique to humans --
-
in all mammals and birds
and some other animals,
-
intelligence and consciousness
go together.
-
We often solve problems by feeling things.
-
So we tend to confuse them.
-
But they are different things.
-
What's happening today
in places like Silicon Valley
-
is that we are creating
artificial intelligence
-
but not artificial consciousness.
-
There has been an amazing development
in computer intelligence
-
over the last 50 years,
-
and exactly zero development
in computer consciousness,
-
and there is no indication that computers
are going to become conscious
-
anytime soon.
-
So first of all, if there is
some cosmic role for consciousness,
-
it's not unique to Homo sapiens.
-
Cows are conscious, pigs are conscious,
-
chimpanzees are conscious,
chickens are conscious,
-
so if we go that way, first of all,
we need to broaden our horizons
-
and remember very clearly we are not
the only sentient beings on Earth,
-
and when it comes to sentience --
-
when it comes to intelligence,
there is good reason to think
-
we are the most intelligent
of the whole bunch.
-
But when it comes to sentience,
-
to say that humans are more
sentient than whales,
-
or more sentient than baboons
or more sentient than cats,
-
I see no evidence for that.
-
So first step is, you go
in that direction, expand.
-
And then the second question
of what is it for,
-
I would reverse it
-
and I would say that I don't think
sentience is for anything.
-
I think we don't need
to find our role in the universe.
-
The really important thing
is to liberate ourselves from suffering.
-
What characterizes sentient beings
-
in contrast to robots, to stones,
-
to whatever,
-
is that sentient beings
suffer, can suffer,
-
and what they should focus on
-
is not finding their place
in some mysterious cosmic drama.
-
They should focus on understanding
what suffering is,
-
what causes it and how
to be liberated from it.
-
CA: I know this is a big issue for you,
and that was very eloquent.
-
We're going to have a blizzard
of questions from the audience here,
-
and maybe from Facebook as well,
-
and maybe some comments as well.
-
So let's go quick.
-
There's one right here.
-
Keep your hands held up
at the back if you want the mic,
-
and we'll get it back to you.
-
Question: In your work, you talk a lot
about the fictional stories
-
that we accept as truth,
-
and we live our lives by it.
-
As an individual, knowing that,
-
how does it impact the stories
that you choose to live your life,
-
and do you confuse them
with the truth, like all of us?
-
YNH: I try not to.
-
I mean, for me, maybe the most
important question,
-
both as a scientist and as a person,
-
is how to tell the difference
between fiction and reality,
-
because reality is there.
-
I'm not saying that everything is fiction.
-
It's just very difficult for human beings
to tell the difference
-
between fiction and reality,
-
and it has become more and more difficult
as history progressed,
-
because the fictions
that we have created --
-
nations and gods and money
and corporations --
-
they now control the world.
-
So just to even think,
-
"Oh, this is just all fictional entities
that we've created,"
-
is very difficult.
-
But reality is there.
-
For me the best ...
-
There are several tests
-
to tell the difference
between fiction and reality.
-
The simplest one, the best one
that I can say in short,
-
is the test of suffering.
-
If it can suffer, it's real.
-
If it can't suffer, it's not real.
-
A nation cannot suffer.
-
That's very, very clear.
-
Even if a nation loses a war,
-
we say, "Germany suffered a defeat
in the First World War,"
-
it's a metaphor.
-
Germany cannot suffer.
Germany has no mind.
-
Germany has no consciousness.
-
Germans can suffer, yes,
but Germany cannot.
-
Similarly, when a bank goes bust,
-
the bank cannot suffer.
-
When the dollar loses its value,
the dollar doesn't suffer.
-
People can suffer. Animals can suffer.
-
This is real.
-
So I would start, if you
really want to see reality,
-
I would go through the door of suffering.
-
If you can really understand
what suffering is,
-
this will give you also the key
-
to understand what reality is.
-
CA: There's a Facebook question
here that connects to this,
-
from someone around the world
in a language that I cannot read.
-
YNH: Oh, it's Hebrew.
CA: Hebrew. There you go.
-
(Laughter)
-
Can you read the name?
-
YNH: [??]
-
CA: Well, thank you for writing in.
-
The question is: "Is the post-truth era
really a brand-new era,
-
or just another climax or moment
in a never-ending trend?
-
YNH: Personally, I don't connect
with this idea of post-truth.
-
My basic reaction as a historian is:
-
If this is the era of post-truth,
when the hell was the era of truth?
-
CA: Right.
-
(Laughter)
-
YNH: Was it the 1980s, the 1950s,
the Middle Ages?
-
I mean, we have always lived
in an era, in a way, of post-truth.
-
CA: But I'd push back on that,
-
because I think what people
are talking about
-
is that there was a world
where you had fewer journalistic outlets,
-
where there were traditions,
that things were fact-checked.
-
It was incorporated into the charter
of those organizations
-
that the truth mattered.
-
So if you believe in a reality,
-
then what you write is information.
-
There was a belief that that information
should connect to reality in a real way,
-
and if you wrote a headline,
it was a serious, earnest attempt
-
to reflect something
that had actually happened.
-
And people didn't always get it right.
-
But I think the concern now is you've got
-
a technological system
that's incredibly powerful
-
that, for a while at least,
massively amplified anything
-
with no attention paid to whether
it connected to reality,
-
only to whether it connected
to clicks and attention,
-
and that that was arguably toxic.
-
That's a reasonable concern, isn't it?
-
YNH: Yeah, it is. I mean,
the technology changes,
-
and it's now easier to disseminate
both truth and fiction and falsehood.
-
It goes both ways.
-
It's also much easier, though, to spread
the truth than it was ever before.
-
But I don't think there
is anything essentially new
-
about this disseminating
fictions and errors.
-
There is nothing that -- I don't know --
Joseph Goebbels, didn't know
-
about all this idea of fake
news and post-truth.
-
He famously said that if you repeat
a lie often enough,
-
people will think it's the truth,
-
and the bigger the lie, the better,
-
because people won't even think
that something so big can be a lie.
-
I think that fake news
has been with us for thousands of years.
-
Just think of the Bible.
-
(Laughter)
-
CA: But there is a concern
-
that the fake news is associated
with tyrannical regimes,
-
and when you see an uprise in fake news
-
that is a canary in the coal mine
that there may be dark times coming.
-
YNH: Yeah. I mean, the intentional use
of fake news is a disturbing sign.
-
But I'm not saying that it's not bad,
I'm just saying that it's not new.
-
CA: There's a lot of interest
on Facebook on this question
-
about global governance
versus nationalism.
-
Question here from Phil Dennis:
-
"How do we get people, governments,
to relinquish power?
-
Is that -- is that --
actually, the text is so big
-
I can't read the full question.
-
But is that a necessity?
-
Is it going to take war to get there?
-
Sorry Phil -- I mangled your question,
but I blame the text right here.
-
YNH: One option
that some people talk about
-
is that only a catastrophe
can shake humankind
-
and open the path to a real system
of global governance,
-
and they say that we can't do it
before the catastrophe,
-
but we need to start
laying the foundations
-
so that when the disaster strikes,
-
we can react quickly.
-
But people will just not have
the motivation to do such a thing
-
before the disaster strikes.
-
Another thing that I would emphasize
-
is that anybody who is really
interested in global governance
-
should always make it very, very clear
-
that it doesn't replace or abolish
local identities and communities,
-
that it should come both as --
-
It should be part of a single package.
-
CA: I want to hear more on this,
-
because the very words "global governance"
-
are almost the epitome of evil
in the mindset of a lot of people
-
on the alt-right right now.
-
It just seems scary, remote, distant,
and it has let them down,
-
and so globalists,
global governance -- no, go away!
-
And many view the election
as the ultimate poke in the eye
-
to anyone who believes in that.
-
So how do we change the narrative
-
so that it doesn't seem
so scary and remote?
-
Build more on this idea
of it being compatible
-
with local identity, local communities.
-
YNH: Well, I think again we should start
-
really with the biological realities
-
of Homo sapiens.
-
And biology tells us two things
about Homo sapiens
-
which are very relevant to this issue:
-
first of all, that we are
completely dependent
-
on the ecological system around us,
-
and that today we are talking
about a global system.
-
You cannot escape that.
-
And at the same time, biology tells us
about Homo sapiens
-
that we are social animals,
-
but that we are social
on a very, very local level.
-
It's just a simple fact of humanity
-
that we cannot have intimate familiarity
-
with more than about 150 individuals.
-
The size of the natural group,
-
the natural community of Homo sapiens,
-
is not more than 150 individuals,
-
and everything beyond that is really
based on all kinds of imaginary stories
-
and large-scale institutions,
-
and I think that we can find a way,
-
again, based on a biological
understanding of our species,
-
to weave the two together
-
and to understand that today
in the 21st century,
-
we need both the global level
and the local community.
-
And I would go even further than that
-
and say that it starts
with the body itself.
-
The feelings that people today have
of alienation and loneliness
-
and not finding their place in the world,
-
I would think that the chief problem
is not global capitalism.
-
The chief problem is that over
the last hundred years,
-
people have been becoming disembodied,
-
have been distancing themselves
from their body.
-
As a hunter-gatherer or even as a peasant,
-
to survive, you need to be
constantly in touch
-
with your body and with your senses,
-
every moment.
-
If you go to the forest
to look for mushrooms
-
and you don't pay attention
to what you hear,
-
to what you smell, to what you taste,
-
you're dead.
-
So you must be very connected.
-
In the last hundred years,
people are losing their ability
-
to be in touch with their body
and their senses,
-
to hear, to smell, to feel.
-
More and more attention goes to screens,
-
to what is happening elsewhere,
-
some other time.
-
This, I think, is the deep reason
-
for the feelings of alienation
and loneliness and so forth,
-
and therefore part of the solution
-
is not to bring back
some mass nationalism,
-
but also reconnect with our own bodies,
-
and if you are back
in touch with your body,
-
you will feel much more at home
in the world also.
-
CA: Well, depending on how things go,
we may all be back in the forest soon.
-
We're going to have
one more question in the room
-
and one more on Facebook.
-
Question: Hello. I'm from Ghana,
West Africa, and my question is:
-
I'm wondering how do you present
and justify the idea of global governance
-
to countries that have been
historically disenfranchised
-
by the effects of globalization,
-
and also, if we're talking about
global governance,
-
it sounds to me like it will definitely
come from a very Westernized idea
-
of what the "global"
is supposed to look like.
-
So how do we present and justify
that idea of global
-
versus wholly nationalist
-
to people in countries like Ghana
and Nigeria and Togo
-
and other countries like that?
-
YNH: I would start by saying
that history is extremely unfair,
-
and that we should realize that.
-
Many of the countries that suffered most
-
from the last 200 years of globalization
-
and imperialism and industrialization
-
are exactly the countries
which are also most likely to suffer most
-
from the next wave.
-
And we should be very,
very clear about that.
-
If we don't have a global governance,
-
and if we suffer from climate change,
-
from technological disruptions,
-
the worst suffering will not be in the US.
-
The worst suffering will be in Ghana,
will be in Sudan, will be in Syria,
-
will be in Bangladesh,
will be in those places.
-
So I think those countries
have an even greater incentive
-
to do something about
the next wave of disruption,
-
whether it's ecological
or whether it's technological.
-
Again, if you think about
technological disruption,
-
so if AI and 3D printers and robots
will take the jobs
-
from billions of people,
-
I worry far less about the Swedes
-
than about the people in Ghana
or in Bangladesh.
-
And therefore,
because history is so unfair
-
and the results of a calamity
-
will not be shared equally
between everybody,
-
as usual, the rich
will be able to get away
-
from the worst consequences
of climate change
-
in a way that the poor
will not be able to.
-
CA: And here's a great question
from Cameron Taylor on Facebook:
-
"At the end of 'Sapiens,'"
-
you said we should be asking the question,
-
'What do we want to want?'
-
Well, what do you think
we should want to want?"
-
YNH: I think we should want
to want to know the truth,
-
to understand reality.
-
Mostly what we want is to change reality,
-
to fit it to our own desires,
to our own wishes,
-
and I think we should first
want to understand it.
-
If you look at the long-term
trajectory of history,
-
what you see is that
for thousands of years
-
we humans have been gaining
control of the world outside us
-
and trying to shape it
to fit our own desires.
-
And we've gained control
of the other animals,
-
of the rivers, of the forests,
-
and reshaped them completely,
-
causing an ecological destruction
-
without making ourselves satisfied.
-
So the next step
is we turn our gaze inwards,
-
and we say OK, getting control
of the world outside us
-
did not really make us satisfied.
-
Let's now try to gain control
of the world inside us.
-
This is the really big project
-
of science and technology
and industry in the 21st century --
-
to try and gain control
of the world inside us,
-
to learn how to engineer and produce
bodies and brains and minds.
-
These are likely to be the main
products of the 21st century economy.
-
When people think about the future,
very often they think in terms,
-
"Oh, I want to gain control
of my body and of my brain."
-
And I think that's very dangerous.
-
If we've learned anything
from our previous history,
-
it's that yes, we gain
the power to manipulate,
-
but because we didn't really
understand the complexity
-
of the ecological system,
-
we are now facing an ecological meltdown.
-
And if we now try to reengineer
the world inside us
-
without really understanding it,
-
especially without understanding
the complexity of our mental system,
-
we might cause a kind of internal
ecological disaster,
-
and we'll face a kind of mental
meltdown inside us.
-
CA: Putting all the pieces
together here --
-
the current politics,
the coming technology,
-
concerns like the one
you've just outlined --
-
I mean, it seems like you yourself
are in quite a bleak place
-
when you think about the future.
-
You're pretty worried about it.
-
Is that right?
-
And if there was one cause for hope,
how would you state that?
-
YNH: I focus on the most
dangerous possibilities
-
partly because this is like
my job or responsibility
-
as a historian or social critic.
-
I mean, the industry focuses mainly
on the positive sides,
-
so it's the job of historians
and philosophers and sociologists
-
to highlight the more dangerous potential
of all these new technologies.
-
I don't think any of that is inevitable.
-
Technology is never deterministic.
-
You can use the same technology
-
to create very different
kinds of societies.
-
If you look at the 20th century,
-
so, the technologies
of the Industrial Revolution,
-
the trains and electricity and all that
-
could be used to create
a communist dictatorship
-
or a fascist regime
or a liberal democracy.
-
The trains did not tell you
what to do with them.
-
Similarly, now, artificial intelligence
and bioengineering and all of that --
-
they don't predetermine a single outcome.
-
Humanity can rise up to the challenge,
-
and the best example we have
-
of humanity rising up
to the challenge of a new technology
-
is nuclear weapons.
-
In the late 1940s, '50s,
-
many people were convinced
-
that sooner or later the Cold War
will end in a nuclear catastrophe,
-
destroying human civilization.
-
And this did not happen.
-
In fact, nuclear weapons prompted
humans all over the world
-
to change the way that they manage
international politics
-
to reduce violence.
-
And many countries basically took out war
-
from their political toolkit.
-
They no longer tried to pursue
their interests with warfare.
-
Not all countries have done so,
but many countries have.
-
And this is maybe
the most important reason
-
why international violence
declined dramatically since 1945,
-
and today, as I said,
more people commit suicide
-
than are killed in war.
-
So this, I think, gives us a good example
-
that even the most frightening technology,
-
humans can rise up to the challenge
-
and actually some good can come out of it.
-
The problem is, we have very little
margin for error.
-
If we don't get it right,
-
we might not have
a second option to try again.
-
CA: That's a very powerful note,
-
on which I think we should draw
this to a conclusion.
-
Before I wrap up, I just want to say
one thing to people here
-
and to the global TED community
watching online, anyone watching online:
-
help us with these dialogues.
-
If you believe, like we do,
-
that we need to find
a different kind of conversation,
-
now more than ever, help us do it.
-
Reach out to other people,
-
try and have conversations
with people you disagree with,
-
understand them,
-
pull the pieces together,
-
and help us figure out how to take
these conversations forward
-
so we can make a real contribution
-
to what's happening
in the world right now.
-
I think everyone feels more alive,
-
more concerned, more engaged
-
with the politics of the moment.
-
The stakes do seem quite high,
-
so help us respond to it
in a wise, wise way.
-
Yuval Harari, thank you.
