Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
that the power is already there,
https://karpathy.ai/lexicap/0001-large.html#00:52:00.080
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
which the focus should be more on being able
https://karpathy.ai/lexicap/0001-large.html#00:52:01.920
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
to communicate with it.
https://karpathy.ai/lexicap/0001-large.html#00:52:05.440
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Well, I agree that in a certain sense,
https://karpathy.ai/lexicap/0001-large.html#00:52:07.360
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
the hardware processing power is already out there
https://karpathy.ai/lexicap/0001-large.html#00:52:11.960
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
because our universe itself can think of it
https://karpathy.ai/lexicap/0001-large.html#00:52:15.360
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
as being a computer already, right?
https://karpathy.ai/lexicap/0001-large.html#00:52:19.000
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
It's constantly computing what water waves,
https://karpathy.ai/lexicap/0001-large.html#00:52:21.000
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
how it devolved the water waves in the River Charles
https://karpathy.ai/lexicap/0001-large.html#00:52:23.800
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
and how to move the air molecules around.
https://karpathy.ai/lexicap/0001-large.html#00:52:26.120
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Seth Lloyd has pointed out, my colleague here,
https://karpathy.ai/lexicap/0001-large.html#00:52:28.440
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
that you can even in a very rigorous way
https://karpathy.ai/lexicap/0001-large.html#00:52:30.480
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
think of our entire universe as being a quantum computer.
https://karpathy.ai/lexicap/0001-large.html#00:52:32.920
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
It's pretty clear that our universe
https://karpathy.ai/lexicap/0001-large.html#00:52:35.480
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
supports this amazing processing power
https://karpathy.ai/lexicap/0001-large.html#00:52:37.680
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
because you can even,
https://karpathy.ai/lexicap/0001-large.html#00:52:40.320
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
within this physics computer that we live in, right?
https://karpathy.ai/lexicap/0001-large.html#00:52:42.160
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
We can even build actual laptops and stuff,
https://karpathy.ai/lexicap/0001-large.html#00:52:44.920
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
so clearly the power is there.
https://karpathy.ai/lexicap/0001-large.html#00:52:47.040
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
It's just that most of the compute power that nature has,
https://karpathy.ai/lexicap/0001-large.html#00:52:49.000
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
it's, in my opinion, kind of wasting on boring stuff
https://karpathy.ai/lexicap/0001-large.html#00:52:52.040
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
like simulating yet another ocean wave somewhere
https://karpathy.ai/lexicap/0001-large.html#00:52:54.240
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
where no one is even looking, right?
https://karpathy.ai/lexicap/0001-large.html#00:52:56.520
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
So in a sense, what life does, what we are doing
https://karpathy.ai/lexicap/0001-large.html#00:52:58.040
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
when we build computers is we're rechanneling
https://karpathy.ai/lexicap/0001-large.html#00:53:00.880
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
all this compute that nature is doing anyway
https://karpathy.ai/lexicap/0001-large.html#00:53:03.880
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
into doing things that are more interesting
https://karpathy.ai/lexicap/0001-large.html#00:53:07.200
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
than just yet another ocean wave,
https://karpathy.ai/lexicap/0001-large.html#00:53:09.360
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
and let's do something cool here.
https://karpathy.ai/lexicap/0001-large.html#00:53:11.440
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
So the raw hardware power is there, for sure,
https://karpathy.ai/lexicap/0001-large.html#00:53:14.080
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
but then even just computing what's going to happen
https://karpathy.ai/lexicap/0001-large.html#00:53:17.080
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
for the next five seconds in this water bottle,
https://karpathy.ai/lexicap/0001-large.html#00:53:21.080
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
takes a ridiculous amount of compute
https://karpathy.ai/lexicap/0001-large.html#00:53:23.520
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
if you do it on a human computer.
https://karpathy.ai/lexicap/0001-large.html#00:53:26.000
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
This water bottle just did it.
https://karpathy.ai/lexicap/0001-large.html#00:53:27.920
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
But that does not mean that this water bottle has AGI
https://karpathy.ai/lexicap/0001-large.html#00:53:29.920
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
because AGI means it should also be able to,
https://karpathy.ai/lexicap/0001-large.html#00:53:34.760
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
like I've written my book, done this interview.
https://karpathy.ai/lexicap/0001-large.html#00:53:37.040
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
And I don't think it's just communication problems.
https://karpathy.ai/lexicap/0001-large.html#00:53:40.160
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
I don't really think it can do it.
https://karpathy.ai/lexicap/0001-large.html#00:53:42.080
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Although Buddhists say when they watch the water
https://karpathy.ai/lexicap/0001-large.html#00:53:46.760
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
and that there is some beauty,
https://karpathy.ai/lexicap/0001-large.html#00:53:49.280
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
that there's some depth and beauty in nature
https://karpathy.ai/lexicap/0001-large.html#00:53:51.240
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
that they can communicate with.
https://karpathy.ai/lexicap/0001-large.html#00:53:53.720
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Communication is also very important though
https://karpathy.ai/lexicap/0001-large.html#00:53:54.840
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
because I mean, look, part of my job is being a teacher.
https://karpathy.ai/lexicap/0001-large.html#00:53:56.480
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
And I know some very intelligent professors even
https://karpathy.ai/lexicap/0001-large.html#00:54:01.200
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
who just have a bit of hard time communicating.
https://karpathy.ai/lexicap/0001-large.html#00:54:06.200
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
They come up with all these brilliant ideas,
https://karpathy.ai/lexicap/0001-large.html#00:54:09.800
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
but to communicate with somebody else,
https://karpathy.ai/lexicap/0001-large.html#00:54:12.640
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
you have to also be able to simulate their own mind.
https://karpathy.ai/lexicap/0001-large.html#00:54:14.520
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Yes, empathy.
https://karpathy.ai/lexicap/0001-large.html#00:54:16.920
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Build well enough and understand model of their mind
https://karpathy.ai/lexicap/0001-large.html#00:54:18.360
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
that you can say things that they will understand.
https://karpathy.ai/lexicap/0001-large.html#00:54:20.640
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
And that's quite difficult.
https://karpathy.ai/lexicap/0001-large.html#00:54:24.400
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
And that's why today it's so frustrating
https://karpathy.ai/lexicap/0001-large.html#00:54:26.480
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
if you have a computer that makes some cancer diagnosis
https://karpathy.ai/lexicap/0001-large.html#00:54:28.280
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
and you ask it, well, why are you saying
https://karpathy.ai/lexicap/0001-large.html#00:54:32.600
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
I should have this surgery?
https://karpathy.ai/lexicap/0001-large.html#00:54:34.120
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
And if it can only reply,
https://karpathy.ai/lexicap/0001-large.html#00:54:36.120
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
I was trained on five terabytes of data
https://karpathy.ai/lexicap/0001-large.html#00:54:37.960
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
and this is my diagnosis, boop, boop, beep, beep.
https://karpathy.ai/lexicap/0001-large.html#00:54:40.800
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
It doesn't really instill a lot of confidence, right?
https://karpathy.ai/lexicap/0001-large.html#00:54:45.080
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
So I think we have a lot of work to do
https://karpathy.ai/lexicap/0001-large.html#00:54:49.120
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
on communication there.
https://karpathy.ai/lexicap/0001-large.html#00:54:51.120
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
So what kind of, I think you're doing a little bit of work
https://karpathy.ai/lexicap/0001-large.html#00:54:54.320
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
in explainable AI.
https://karpathy.ai/lexicap/0001-large.html#00:54:58.040
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
What do you think are the most promising avenues?
https://karpathy.ai/lexicap/0001-large.html#00:54:59.320
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Is it mostly about sort of the Alexa problem
https://karpathy.ai/lexicap/0001-large.html#00:55:01.320
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
of natural language processing of being able
https://karpathy.ai/lexicap/0001-large.html#00:55:05.240
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
to actually use human interpretable methods
https://karpathy.ai/lexicap/0001-large.html#00:55:07.200
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
of communication?
https://karpathy.ai/lexicap/0001-large.html#00:55:11.600
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
So being able to talk to a system and it talk back to you,
https://karpathy.ai/lexicap/0001-large.html#00:55:13.160
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
or is there some more fundamental problems to be solved?
https://karpathy.ai/lexicap/0001-large.html#00:55:16.000
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
I think it's all of the above.
https://karpathy.ai/lexicap/0001-large.html#00:55:18.640
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
The natural language processing is obviously important,
https://karpathy.ai/lexicap/0001-large.html#00:55:21.160
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
but there are also more nerdy fundamental problems.
https://karpathy.ai/lexicap/0001-large.html#00:55:23.520
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Like if you take, you play chess?
https://karpathy.ai/lexicap/0001-large.html#00:55:27.600
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Of course, I'm Russian.
https://karpathy.ai/lexicap/0001-large.html#00:55:31.640
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
I have to.
https://karpathy.ai/lexicap/0001-large.html#00:55:33.040
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
You speak Russian?
https://karpathy.ai/lexicap/0001-large.html#00:55:33.880
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Yes, I speak Russian.
https://karpathy.ai/lexicap/0001-large.html#00:55:34.720
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Excellent, I didn't know.
https://karpathy.ai/lexicap/0001-large.html#00:55:35.560
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
When did you learn Russian?
https://karpathy.ai/lexicap/0001-large.html#00:55:38.040
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
I speak very bad Russian, I'm only an autodidact,
https://karpathy.ai/lexicap/0001-large.html#00:55:39.160
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
but I bought a book, Teach Yourself Russian,
https://karpathy.ai/lexicap/0001-large.html#00:55:41.800
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
read a lot, but it was very difficult.
https://karpathy.ai/lexicap/0001-large.html#00:55:44.560
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Wow.
https://karpathy.ai/lexicap/0001-large.html#00:55:47.720
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
That's why I speak so bad.
https://karpathy.ai/lexicap/0001-large.html#00:55:48.560
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
How many languages do you know?
https://karpathy.ai/lexicap/0001-large.html#00:55:49.960
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Wow, that's really impressive.
https://karpathy.ai/lexicap/0001-large.html#00:55:51.960
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
I don't know, my wife has some calculation,
https://karpathy.ai/lexicap/0001-large.html#00:55:53.840
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
but my point was, if you play chess,
https://karpathy.ai/lexicap/0001-large.html#00:55:56.320
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
have you looked at the AlphaZero games?
https://karpathy.ai/lexicap/0001-large.html#00:55:58.400
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
The actual games, no.
https://karpathy.ai/lexicap/0001-large.html#00:56:01.040
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
Check it out, some of them are just mind blowing,
https://karpathy.ai/lexicap/0001-large.html#00:56:02.600
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
really beautiful.
https://karpathy.ai/lexicap/0001-large.html#00:56:06.320
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
And if you ask, how did it do that?
https://karpathy.ai/lexicap/0001-large.html#00:56:07.720
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
You go talk to Demis Hassabis,
https://karpathy.ai/lexicap/0001-large.html#00:56:13.760
Max Tegmark: Life 3.0 | Lex Fridman Podcast #1
I know others from DeepMind,
https://karpathy.ai/lexicap/0001-large.html#00:56:16.520
