1
00:00:00,410 --> 00:00:02,160
Siri, are you artificial intelligence?

2
00:00:02,160 --> 00:00:04,223
SIRI: Close enough, I'd say.

3
00:00:06,100 --> 00:00:09,090
Artificial intelligence is
when humans train computers

4
00:00:09,090 --> 00:00:11,910
to recreate the workings
of the human brain.

5
00:00:11,910 --> 00:00:13,380
AI occurs when machines

6
00:00:13,380 --> 00:00:15,227
have learned to recognize enough patterns

7
00:00:15,227 --> 00:00:18,267
to be able to make decisions on their own.

8
00:00:21,500 --> 00:00:24,403
Episode 4, Artificial Intelligence.

9
00:00:28,520 --> 00:00:30,430
So what does that actually look like?

10
00:00:30,430 --> 00:00:32,347
Here's how Google uses
artificial intelligence

11
00:00:32,347 --> 00:00:34,550
to write email replies for you.

12
00:00:34,550 --> 00:00:38,010
An email comes in. It says,
are you free tomorrow?

13
00:00:38,010 --> 00:00:40,950
It moves through the thought
vector, which is a black box.

14
00:00:40,950 --> 00:00:43,980
And what comes out the other
end is the AI response.

15
00:00:43,980 --> 00:00:45,433
Yes, what's up?

16
00:00:47,990 --> 00:00:49,950
But AI can go horribly wrong.

17
00:00:49,950 --> 00:00:51,100
Google was using AI

18
00:00:51,100 --> 00:00:53,900
to tag images that were
uploaded to the web.

19
00:00:53,900 --> 00:00:56,380
Google's AI engine started to tag images

20
00:00:56,380 --> 00:00:58,470
of black people as gorillas.

21
00:00:58,470 --> 00:01:01,150
The company apologized and
said they would fix it.

22
00:01:01,150 --> 00:01:03,678
AI is only as good as
the patterns we teach it.

23
00:01:03,678 --> 00:01:06,100
So if we give it biased, stereotyped,

24
00:01:06,100 --> 00:01:08,740
or even racist information, what then?

25
00:01:08,740 --> 00:01:11,438
In one study, researchers
trained an AI program

26
00:01:11,438 --> 00:01:14,910
with 3 million words from
Google news articles.

27
00:01:14,910 --> 00:01:16,290
This is what they found.

28
00:01:16,290 --> 00:01:19,893
The closest word to the query
black male, returns assaulted.

29
00:01:24,090 --> 00:01:26,843
While the response to
white male, is entitled to.

30
00:01:31,610 --> 00:01:34,530
If we're not intelligent
about how we train our robots,

31
00:01:34,530 --> 00:01:37,323
they will perpetuate the
worst of human behavior.
