True Artificial Intelligence will change everything | Juergen Schmidhuber | TEDxLakeComo

  • 0:02 - 0:06
    [Music]
  • 0:06 - 0:15
    When I was a boy I wanted to maximize
    my impact on the world and I was
  • 0:15 - 0:24
    smart enough to realize that I am
    not very smart and that I have to build
  • 0:24 - 0:30
    a machine that learns to become
    much smarter than myself such that it
  • 0:30 - 0:35
    can solve all the problems that I
    cannot solve myself and
  • 0:35 - 0:36
    I can retire.
  • 0:37 - 0:45
    And my first publication on that dates
    back 30 years 1987 my diploma thesis where
  • 0:45 - 0:50
    I already try to solve the grand problem
    of AI not only build a machine that learns
  • 0:50 - 0:56
    a little bit here and learns a little bit
    there but also learns to improve the
  • 0:56 - 1:03
    learning algorithm itself and the way it
    learns the way it learns and so on
  • 1:03 - 1:13
    recursively without any limits except
    the limits of logics and physics and
  • 1:13 - 1:16
    I'm still working on
    the same old thing and I'm
  • 1:16 - 1:25
    still pretty much saying the same thing
    except that now more people are listening
  • 1:25 - 1:30
    because the learning algorithms that we
    have developed on the way to
  • 1:30 - 1:35
    this goal they are now on
    three thousand million smartphones and all
  • 1:35 - 1:41
    of you have them in your pockets what you
    see here are
  • 1:41 - 1:45
    the five most valuable companies of the
  • 1:45 - 1:48
    Western world Apple Google Facebook
  • 1:48 - 1:57
    Microsoft and Amazon and all of them
    are emphasizing that AI
  • 1:57 - 2:05
    artificial intelligence is central to what
    they are doing and all of them are using
  • 2:05 - 2:11
    heavily the deep learning methods that
    my team has developed since
  • 2:11 - 2:16
    the early nineties and yone in Munich and
    in Switzerland especially something which
  • 2:16 - 2:22
    is called so long short term memory has
    anybody in this room ever heard of
  • 2:22 - 2:28
    the long short-term memory or
    the LST M hands up anybody ever heard
  • 2:28 - 2:37
    of that okay has anybody never heard of
    the STM I see we have a third group in
  • 2:37 - 2:53
    this room who didn't understand
    the question the lsdm is a little bit like
  • 2:53 - 2:55
    your brain it's
    an artificial neural network which
  • 2:55 - 3:01
    also has neurons and in
    your brain you've got about
  • 3:01 - 3:06
    100 billion neurons and each of them
    is connected to roughly
  • 3:06 - 3:13
    10,000 other neurons on average which
    means that you have got
  • 3:13 - 3:20
    a million billion connections and each of
    these connections has a strength which
  • 3:20 - 3:24
    says how much does this neuron over
    here influence that neuron over there at
  • 3:24 - 3:29
    the next time step and in the beginning
    all these connections are random and
  • 3:29 - 3:34
    the system knows nothing within through a
    smart learning algorithm it learns from
  • 3:34 - 3:42
    lots of examples to translate
    the incoming data such as video through
  • 3:42 - 3:48
    the cameras or audio through
    the microphones or pain signals through
  • 3:48 - 3:53
    the pain sensors it learns to translate
    that into output actions because some of
  • 3:53 - 3:55
    these neurons are output neurons that
    control
  • 3:55 - 4:03
    speech muscles and finger muscles and only
    through experience it can learn to solve
  • 4:03 - 4:13
    all kinds of interesting problems such as
    driving a car or do the speech recognition
  • 4:13 - 4:17
    on your smartphone because whenever you
    take out your smartphone an
  • 4:17 - 4:22
    Android phone for example and you speak to
    it and you say ok Google show me is
  • 4:22 - 4:28
    the shortest way to Milano then it
    understands your speech because there is
  • 4:28 - 4:31
    an lsdm in there which
    has learned to understand
  • 4:31 - 4:33
    speech every 10 milliseconds
  • 4:33 - 4:40
    100 times a second new inputs are coming
    from the microphone and then translates it
  • 4:40 - 4:49
    after thinking into letters which is then
    question to the search engine and it has
  • 4:49 - 4:54
    long to do that by listening to lots of
    speech from women from me all kinds of
  • 4:55 - 4:57
    people and that's how since
  • 4:57 - 5:01
    2015 Google speech recognition is
    now much better than it used to be
  • 5:02 - 5:08
    the basic lsdm cell looks like that I
    don't have the time to explain that but at
  • 5:08 - 5:14
    least I can list the names of
    the brilliant students in my lab who made
  • 5:14 - 5:18
    that possible and what are
    the big companies doing with
  • 5:18 - 5:26
    that well speech recognition is only
    one example if you are on Facebook is
  • 5:26 - 5:29
    anybody on Facebook okay I
    use sometimes clicking at
  • 5:29 - 5:33
    the translate button because somebody sent
    you something in a foreign language and
  • 5:33 - 5:38
    then you can translate it is anybody
    doing that yeah whatever you do that you
  • 5:38 - 5:42
    are waking up again
    a long short term memory and lsdm which
  • 5:42 - 5:49
    has learned to translate text in
    one language into translated text and
  • 5:49 - 5:57
    Facebook is doing that four billion times
    a day so every 50 every second
  • 5:57 - 6:03
    50,000 sentences are being translated by
    an LST am working for
  • 6:04 - 6:06
    Facebook and another 50,000 in the
    second and another
  • 6:06 - 6:13
    50,000 and to see how much this thing
    is now permitting the modern world
  • 6:13 - 6:21
    just note that almost 30 percent of
    the awesome computational power for
  • 6:21 - 6:24
    interference and all these Google Data
  • 6:24 - 6:29
    Centers all these data centers of Google
    are all over the world is used for LST on
  • 6:29 - 6:32
    almost 30 percent if you have an
  • 6:32 - 6:39
    Amazon echo you can ask a questions and it
    answers you and the voice that you hear
  • 6:39 - 6:43
    it's not a recording it's
    an LS TM network which has learned from
  • 6:43 - 6:54
    training examples to sound like
    a female voice if you have an iPhone and
  • 6:54 - 6:57
    you're using
    the quick type it's trying to predict what
  • 6:57 - 7:00
    you want to do next given
    all the previous context of what you did
  • 7:00 - 7:05
    so far again that's an LS DM which
    has to do that so it's on
  • 7:05 - 7:15
    a billion iPhones you are a large audience
    by my standards but when we started
  • 7:15 - 7:22
    this work decades ago in the early
    90s only few people who were interested
  • 7:22 - 7:26
    in that because computers were so slow and
    you couldn't do so much with it and I
  • 7:26 - 7:33
    remember I gave a talk at
    a conference and there was just
  • 7:33 - 7:37
    one single person in the audience
    a young lady I said young lady it's
  • 7:38 - 7:42
    very embarrassing but apparently
    today I'm going to give this talk just to
  • 7:42 - 7:54
    you and she said okay but please hurry I
    am the next speaker since then we
  • 7:54 - 8:01
    have greatly profited from the fact
    that every five years computers again in
  • 8:01 - 8:06
    ten times cheaper which is
    an old trend that has held since 1941 at
  • 8:06 - 8:12
    least since this man Conrad Susan built
    the first working program control computer
  • 8:12 - 8:20
    in Berlin and he could could do roughly
    one operation per second one and then
  • 8:20 - 8:26
    ten years later for the same prize one
    could do 100 operations 30 years later
  • 8:26 - 8:30
    1 million operations were
    the same price and today after 75 years we
  • 8:30 - 8:35
    can do a million billion times as much for
    the same price and the trend is not about
  • 8:35 - 8:44
    to stop because the physical limits are
    much further out there rather soon and not
  • 8:45 - 8:49
    so many years or decades we will for
    the first time have
  • 8:49 - 8:55
    little computational devices that
    can compute as much as a human brain and
  • 8:55 - 8:59
    this a trend doesn't break 50 years
    later there will be
  • 8:59 - 9:04
    a little computational device for
    the same price that can compute as much as
  • 9:04 - 9:10
    all 10 billion human brains taken
    together and there will not only be one of
  • 9:10 - 9:13
    those devices but
    many many many everything
  • 9:13 - 9:18
    is going to change already in
    2011 computers were fast enough such that
  • 9:18 - 9:22
    our deep learning methods for
    the first time could achieve
  • 9:22 - 9:28
    a superhuman pattern-recognition result and
    was the first superhuman result and
  • 9:28 - 9:32
    the history of
    computer vision and back then computers
  • 9:32 - 9:36
    were 20 times more expensive than today so
    today for the same price we can do
  • 9:36 - 9:45
    20 times as much and just a few five years
    ago five years ago when computers were
  • 9:45 - 9:50
    10 times more expensive than today we
    already could win for the first time
  • 9:50 - 9:54
    medical imaging competitions what you see
    behind me is a slice through
  • 9:54 - 10:00
    the female breast and the tissue that you
    see there has all kinds of
  • 10:00 - 10:05
    cells and normally you need
    a trained doctor a trained the solid who
  • 10:05 - 10:10
    is able to detect
    the dangerous cancer cells or
  • 10:10 - 10:15
    pre-cancer cells now our stupid network
    knows nothing about cancer knows nothing
  • 10:15 - 10:19
    about vision it knows nothing in
    the beginning but we can train it
  • 10:19 - 10:25
    to imitate the human teacher
    the doctor and it became as good or better
  • 10:25 - 10:31
    than the best competitors and
    very soon all of medical diagnosis
  • 10:31 - 10:36
    is going to be superhuman and
    it's going to be mandatory because
  • 10:36 - 10:42
    it's going to be so much better than
    the doctors after this all kinds of
  • 10:42 - 10:48
    medical imaging startups
    were founded focusing just on this because
  • 10:48 - 10:54
    it's so important we can also use lsdm
    to train robots one important thing I
  • 10:54 - 11:01
    want to say is that we not only have
    systems that slavishly imitate what humans
  • 11:01 - 11:09
    show them no we also have a eyes that set
    themselves their own goals and
  • 11:09 - 11:14
    like little babies invent
    their own experiment to explore
  • 11:14 - 11:19
    the world and to figure out what you
    can do in the world without a teacher and
  • 11:19 - 11:23
    becoming more and
    more general problem solvers in
  • 11:23 - 11:28
    the process by learning new skills on top
    of old skills and this is going to
  • 11:28 - 11:34
    scale we call that artificial curiosity or
    a recent password is power plain
  • 11:34 - 11:39
    learning to become a more and
    more general problems over by
  • 11:40 - 11:44
    learning to invent like a scientist
    one new interesting goal after
  • 11:45 - 11:50
    Nathan and and it's going to scale and I
    think in not so many years from now for
  • 11:50 - 11:56
    the first time we are going to have
    an animal like
  • 11:56 - 12:01
    AI you don't have that yet on the level of
    a little crowd which
  • 12:01 - 12:07
    already can learn to use two worlds for
    example little monkey and once we have
  • 12:07 - 12:11
    that it may take just a few decades to do
    the final step towards
  • 12:11 - 12:17
    human level intelligence because
    technological evolution is about
  • 12:17 - 12:22
    a million times a million times faster
    than biological evolution and
  • 12:22 - 12:30
    biological evolution needed
    3.5 billion years to evolve a monkey
  • 12:30 - 12:34
    a monkey from scratch but then just
    a few tens of millions of years
  • 12:34 - 12:39
    afterwards to evolve
    human level intelligence we have
  • 12:39 - 12:43
    a company which is called Mason's
    like birth in English
  • 12:43 - 12:47
    Mason's but spelled in
    a different way which is trying to make
  • 12:47 - 12:51
    this a reality and build
    the first true general and purpose AI at
  • 12:53 - 13:00
    the moment almost all research in AI is
    very human centric and it's all about
  • 13:00 - 13:06
    making human lives longer and
    healthier and easier and making humans
  • 13:06 - 13:12
    more addicted to their smartphones but
    in the long run a eyes are going to
  • 13:12 - 13:17
    especially the smart ones are going to set
    themselves their own goals and I have
  • 13:17 - 13:22
    no doubt in my mind that they
    are going to become much smarter than we
  • 13:22 - 13:26
    are and what are they going to do of
    course they are going to realize what we
  • 13:26 - 13:31
    have realized a long time ago namely that
    most of the resources in
  • 13:31 - 13:38
    the solar system or in general are not in
    our little biosphere they are out there in
  • 13:38 - 13:44
    space and so of course they
    are going to emigrate and of course they
  • 13:44 - 13:53
    are going to use trillions of
    self-replicating robot factories to expand
  • 13:54 - 13:57
    in form of growing
  • 13:57 - 14:01
    AI bubble which within a few
    hundred thousand years is going to cover
  • 14:01 - 14:07
    the entire galaxy by senders and receivers
    such that a eyes can travel the way they
  • 14:07 - 14:16
    are already traveling in my lab by radio
    from sender to receiver Wireless so what
  • 14:16 - 14:23
    we are witnessing now is much more than
    just another Industrial Revolution this is
  • 14:24 - 14:29
    something that transcends
    humankind and even life itself
  • 14:29 - 14:35
    the last time something so important
    has happened was maybe 3.5 billion years
  • 14:35 - 14:42
    ago when life was invented a new type of
    life is going to emerge from
  • 14:42 - 14:46
    our little planet and
    it's going to colonize and transform
  • 14:47 - 14:52
    the entire universe the universe is
    still young it's only 13.8 billion years
  • 14:52 - 14:58
    old it's going to become much older than
    that many times more many times older
  • 14:58 - 15:03
    than that so there's plenty of time
    to reach all of it or all of
  • 15:03 - 15:09
    the visible parts totally within
    the limits of light speed and physics
  • 15:10 - 15:15
    a new type of life is going to make
    the universe intelligent now of course we
  • 15:15 - 15:22
    are not going to remain the crown of
    creation of course not but there is still
  • 15:22 - 15:29
    beauty in seeing yourself as part of
    a grander process that leads the cosmos
  • 15:29 - 15:36
    from low complexity towards
    higher complexity it's a privilege to live
  • 15:36 - 15:40
    at a time where we can
    witness the beginnings of that and where
  • 15:40 - 15:50
    we can contribute something to
    that thank you for your patience
