Christof Koch: Consciousness | Lex Fridman Podcast #2
|
he talks about this very vividly.
|
https://karpathy.ai/lexicap/0002-large.html#00:50:30.080
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And finally, the dominant machine intelligence organism that survived were gigantic clouds
|
https://karpathy.ai/lexicap/0002-large.html#00:50:32.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
of little hexagonal universal cellular automata.
|
https://karpathy.ai/lexicap/0002-large.html#00:50:39.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
This was written in the 60s, so typically they're all lying on the ground individual
|
https://karpathy.ai/lexicap/0002-large.html#00:50:42.520
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
by themselves, but in times of crisis, they can communicate, they assemble into gigantic
|
https://karpathy.ai/lexicap/0002-large.html#00:50:46.560
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
nets into clouds of trillions of these particles and then they become hyper intelligent and
|
https://karpathy.ai/lexicap/0002-large.html#00:50:50.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
they can beat anything that humans can throw at it.
|
https://karpathy.ai/lexicap/0002-large.html#00:50:55.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
It's very beautiful and compelling where you have an intelligence where finally the humans
|
https://karpathy.ai/lexicap/0002-large.html#00:51:00.000
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
leave the planet, they're simply unable to understand and comprehend this creature.
|
https://karpathy.ai/lexicap/0002-large.html#00:51:05.080
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
They can say, well, either we can nuke the entire planet and destroy it or we just have
|
https://karpathy.ai/lexicap/0002-large.html#00:51:09.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
to leave because fundamentally it's an alien, it's so alien from us and our ideas that we
|
https://karpathy.ai/lexicap/0002-large.html#00:51:13.160
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
cannot communicate with them.
|
https://karpathy.ai/lexicap/0002-large.html#00:51:18.480
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Yeah, actually in conversation, so you're talking to us, Steven Wolf from Brought Up
|
https://karpathy.ai/lexicap/0002-large.html#00:51:20.280
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
is that there could be ideas that you already have these artificial general intelligence
|
https://karpathy.ai/lexicap/0002-large.html#00:51:25.960
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
like super smart or maybe conscious beings in the cellular automata, we just don't know
|
https://karpathy.ai/lexicap/0002-large.html#00:51:32.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
how to talk to them.
|
https://karpathy.ai/lexicap/0002-large.html#00:51:36.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So it's the language of communication, but you don't know what to do with it.
|
https://karpathy.ai/lexicap/0002-large.html#00:51:37.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So that's one sort of view is consciousness is only something you can measure.
|
https://karpathy.ai/lexicap/0002-large.html#00:51:41.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So it's not conscious if you can't measure it.
|
https://karpathy.ai/lexicap/0002-large.html#00:51:46.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So you're making an ontological and an epistemic statement.
|
https://karpathy.ai/lexicap/0002-large.html#00:51:50.160
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
One is it's just like seeing the multiverses, that might be true, but I can't communicate
|
https://karpathy.ai/lexicap/0002-large.html#00:51:53.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
with them.
|
https://karpathy.ai/lexicap/0002-large.html#00:51:59.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
I can't have any knowledge of them.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:00.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
That's an epistemic argument.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:01.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Right?
|
https://karpathy.ai/lexicap/0002-large.html#00:52:02.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So those are two different things.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:03.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So it may well be possible.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:04.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Look, in another case that's happening right now, people are building these mini organoids.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:05.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Do you know what this is?
|
https://karpathy.ai/lexicap/0002-large.html#00:52:09.320
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So you can take stem cells from under your arm, put it in a dish, add four transcription
|
https://karpathy.ai/lexicap/0002-large.html#00:52:10.960
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
factors and then you can induce them to grow into large, well, large, they're a few millimeters.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:14.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
They're like a half a million neurons that look like nerve cells in a dish called mini
|
https://karpathy.ai/lexicap/0002-large.html#00:52:19.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
organoids at Harvard, at Stanford, everywhere they're building them.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:23.540
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
It may well be possible that they're beginning to feel like something, but we can't really
|
https://karpathy.ai/lexicap/0002-large.html#00:52:27.300
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
communicate with them right now.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:31.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So people are beginning to think about the ethics of this.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:33.560
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So yes, he may be perfectly right, but it's one question, are they conscious or not?
|
https://karpathy.ai/lexicap/0002-large.html#00:52:36.400
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
It's a totally separate question.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:41.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
How would I know?
|
https://karpathy.ai/lexicap/0002-large.html#00:52:43.040
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Those are two different things.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:44.040
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
If you could give advice to a young researcher, sort of dreaming of understanding or creating
|
https://karpathy.ai/lexicap/0002-large.html#00:52:45.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
human level intelligence or consciousness, what would you say?
|
https://karpathy.ai/lexicap/0002-large.html#00:52:52.940
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Just follow your dreams.
|
https://karpathy.ai/lexicap/0002-large.html#00:52:59.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Read widely.
|
https://karpathy.ai/lexicap/0002-large.html#00:53:01.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
No, I mean, I suppose with discipline, what is the pursuit that they should take on?
|
https://karpathy.ai/lexicap/0002-large.html#00:53:02.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Is it neuroscience?
|
https://karpathy.ai/lexicap/0002-large.html#00:53:08.880
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Is it computational cognitive science?
|
https://karpathy.ai/lexicap/0002-large.html#00:53:09.880
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Is it philosophy?
|
https://karpathy.ai/lexicap/0002-large.html#00:53:11.700
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Is it computer science or robotics?
|
https://karpathy.ai/lexicap/0002-large.html#00:53:12.700
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
No, in a sense that, okay, so the only known system that have high level of intelligence
|
https://karpathy.ai/lexicap/0002-large.html#00:53:15.400
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
is homo sapiens.
|
https://karpathy.ai/lexicap/0002-large.html#00:53:22.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So if you wanted to build it, it's probably good to continue to study closely what humans
|
https://karpathy.ai/lexicap/0002-large.html#00:53:24.480
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
do.
|
https://karpathy.ai/lexicap/0002-large.html#00:53:28.480
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So cognitive neuroscience, you know, somewhere between cognitive neuroscience on the one hand
|
https://karpathy.ai/lexicap/0002-large.html#00:53:29.480
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
and some philosophy of mind and then AI, AI computer science.
|
https://karpathy.ai/lexicap/0002-large.html#00:53:32.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You can look at all the original ideas in your network, they all came from neuroscience,
|
https://karpathy.ai/lexicap/0002-large.html#00:53:37.360
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
right?
|
https://karpathy.ai/lexicap/0002-large.html#00:53:42.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Reinforce whether it's Snarky, Minsky building is Snarky or whether it's, you know, the early
|
https://karpathy.ai/lexicap/0002-large.html#00:53:43.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Hubel and Wiesel experiments at Harvard that then gave rise to networks and then multi
|
https://karpathy.ai/lexicap/0002-large.html#00:53:47.360
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
layer networks.
|
https://karpathy.ai/lexicap/0002-large.html#00:53:50.960
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So it may well be possible, in fact, some people argue that to make the next big step
|
https://karpathy.ai/lexicap/0002-large.html#00:53:52.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
in AI once we realize the limits of deep convolutional networks, they can do certain things, but
|
https://karpathy.ai/lexicap/0002-large.html#00:53:57.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
they can't really understand.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:02.680
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
They don't, they can't really, I can't really show them one image.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:03.680
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
I can show you a single image of somebody, a pickpocket who steals a wallet from a purse.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:08.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You immediately know that's a pickpocket.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:14.880
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Now computer system would just say, well, it's a man, it's a woman, it's a purse, right?
|
https://karpathy.ai/lexicap/0002-large.html#00:54:17.040
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Unless you train this machine on showing it a hundred thousand pickpockets, right?
|
https://karpathy.ai/lexicap/0002-large.html#00:54:21.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So it doesn't have this easy understanding that you have, right?
|
https://karpathy.ai/lexicap/0002-large.html#00:54:24.520
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So some people make the argument in order to go to the next step or you really want
|
https://karpathy.ai/lexicap/0002-large.html#00:54:29.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
to build machines that understand in a way you and I, we have to go to psychology.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:33.000
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
We need to understand how we do it and how our brains enable us to do it.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:37.140
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And so therefore being on the cusp, it's also so exciting to try to understand better our
|
https://karpathy.ai/lexicap/0002-large.html#00:54:40.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
nature and then to build, to take some of those inside and build them.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:45.040
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So I think the most exciting thing is somewhere in the interface between cognitive science,
|
https://karpathy.ai/lexicap/0002-large.html#00:54:48.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
neuroscience, AI, computer science and philosophy of mind.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:52.720
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Beautiful.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:55.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Yeah.
|
https://karpathy.ai/lexicap/0002-large.html#00:54:56.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
I'd say if there is from the machine learning, from our, from the computer science, computer
|
https://karpathy.ai/lexicap/0002-large.html#00:54:57.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
vision perspective, many of the researchers kind of ignore the way the human brain works
|
https://karpathy.ai/lexicap/0002-large.html#00:55:00.520
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
or even psychology or literature or studying the brain, I would hope Josh Tenenbaum talks
|
https://karpathy.ai/lexicap/0002-large.html#00:55:05.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
about bringing that in more and more.
|
https://karpathy.ai/lexicap/0002-large.html#00:55:12.160
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And that's, yeah, so you've worked on some amazing stuff throughout your life.
|
https://karpathy.ai/lexicap/0002-large.html#00:55:14.760
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
What's the thing that you're really excited about?
|
https://karpathy.ai/lexicap/0002-large.html#00:55:20.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
What's the mystery that you would love to uncover in the near term beyond, beyond all
|
https://karpathy.ai/lexicap/0002-large.html#00:55:24.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
the mysteries that you're already surrounded by?
|
https://karpathy.ai/lexicap/0002-large.html#00:55:30.560
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Well, so there's a structure called the claustrum.
|
https://karpathy.ai/lexicap/0002-large.html#00:55:32.400
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
This is a structure, it's underneath our cortex, it's yay big.
|
https://karpathy.ai/lexicap/0002-large.html#00:55:36.720
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You have one on the left, on the right, underneath this, underneath the insula, it's very thin,
|
https://karpathy.ai/lexicap/0002-large.html#00:55:40.040
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
it's like one millimeter, it's embedded in, in wiring, in white matter, so it's very difficult
|
https://karpathy.ai/lexicap/0002-large.html#00:55:44.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
to image.
|
https://karpathy.ai/lexicap/0002-large.html#00:55:48.280
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And it has, it has connection to every cortical region.
|
https://karpathy.ai/lexicap/0002-large.html#00:55:50.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And Francis Crick, the last paper he ever wrote, he dictated corrections the day he
|
https://karpathy.ai/lexicap/0002-large.html#00:55:55.080
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
died in hospital on this paper.
|
https://karpathy.ai/lexicap/0002-large.html#00:55:58.360
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You know, we hypothesize, well, because it has this unique anatomy, it gets input from
|
https://karpathy.ai/lexicap/0002-large.html#00:56:00.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
every cortical area and projects back to every, every cortical area.
|
https://karpathy.ai/lexicap/0002-large.html#00:56:05.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
That the function of this structure is similar, it's just a metaphor to the role of a conductor
|
https://karpathy.ai/lexicap/0002-large.html#00:56:10.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
in a symphony orchestra.
|
https://karpathy.ai/lexicap/0002-large.html#00:56:16.760
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You have all the different cortical players.
|
https://karpathy.ai/lexicap/0002-large.html#00:56:18.760
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You have some that do motion, some that do theory of mind, some that infer social interaction
|
