Christof Koch: Consciousness | Lex Fridman Podcast #2
|
There is the concept of intelligence, natural or artificial, and there is a concept of consciousness,
|
https://karpathy.ai/lexicap/0002-large.html#00:07:39.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
of experience, natural or artificial.
|
https://karpathy.ai/lexicap/0002-large.html#00:07:45.160
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Those are very, very different things.
|
https://karpathy.ai/lexicap/0002-large.html#00:07:47.400
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Now, historically, we associate consciousness with intelligence.
|
https://karpathy.ai/lexicap/0002-large.html#00:07:49.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Why?
|
https://karpathy.ai/lexicap/0002-large.html#00:07:53.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Because we live in a world, leaving aside computers, of natural selection, where we're
|
https://karpathy.ai/lexicap/0002-large.html#00:07:54.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
surrounded by creatures, either our own kin that are less or more intelligent, or we go
|
https://karpathy.ai/lexicap/0002-large.html#00:07:59.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
across species.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:04.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Some are more adapted to a particular environment.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:06.040
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Others are less adapted, whether it's a whale or dog, or you go talk about a paramecium
|
https://karpathy.ai/lexicap/0002-large.html#00:08:08.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
or a little worm.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:12.760
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And we see the complexity of the nervous system goes from one cell to specialized cells, to
|
https://karpathy.ai/lexicap/0002-large.html#00:08:15.040
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
a worm that has three nets, that has 30 percent of its cells are nerve cells, to creature
|
https://karpathy.ai/lexicap/0002-large.html#00:08:21.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
like us or like a blue whale that has 100 billion, even more nerve cells.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:26.000
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And so based on behavioral evidence and based on the underlying neuroscience, we believe
|
https://karpathy.ai/lexicap/0002-large.html#00:08:30.160
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
that as these creatures become more complex, they are better adapted to their particular
|
https://karpathy.ai/lexicap/0002-large.html#00:08:35.160
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
ecological niche, and they become more conscious, partly because their brain grows.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:40.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And we believe consciousness, unlike the ancient, ancient people thought most, almost every
|
https://karpathy.ai/lexicap/0002-large.html#00:08:46.520
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
culture thought that consciousness with intelligence has to do with your heart.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:50.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And you still see that today.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:55.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You see, honey, I love you with all my heart.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:56.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
But what you should actually say is, no, honey, I love you with all my lateral hypothalamus.
|
https://karpathy.ai/lexicap/0002-large.html#00:08:59.420
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And for Valentine's Day, you should give your sweetheart, you know, hypothalamus, a piece
|
https://karpathy.ai/lexicap/0002-large.html#00:09:04.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
of chocolate and not a heart shaped chocolate.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:09.280
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Anyway, so we still have this language, but now we believe it's a brain.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:11.400
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And so we see brains of different complexity and we think, well, they have different levels
|
https://karpathy.ai/lexicap/0002-large.html#00:09:14.560
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
of consciousness.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:18.720
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
They're capable of different experiences.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:19.720
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
But now we confront the world where we know where we're beginning to engineer intelligence.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:25.300
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And it's radical unclear whether the intelligence we're engineering has anything to do with
|
https://karpathy.ai/lexicap/0002-large.html#00:09:32.040
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
consciousness and whether it can experience anything.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:37.080
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Because fundamentally, what's the difference?
|
https://karpathy.ai/lexicap/0002-large.html#00:09:40.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Intelligence is about function.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:42.900
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Intelligence no matter exactly how you define it, sort of adaptation to new environments,
|
https://karpathy.ai/lexicap/0002-large.html#00:09:44.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
being able to learn and quickly understand, you know, the setup of this and what's going
|
https://karpathy.ai/lexicap/0002-large.html#00:09:48.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
on and who are the actors and what's going to happen next.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:53.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
That's all about function.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:55.900
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Consciousness is not about function.
|
https://karpathy.ai/lexicap/0002-large.html#00:09:58.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Consciousness is about being.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:00.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
It's in some sense much fundamental.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:02.420
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You can see this in several cases.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:05.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You can see it, for instance, in the case of the clinic.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:08.760
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
When you're dealing with patients who are, let's say, had a stroke or had were in traffic
|
https://karpathy.ai/lexicap/0002-large.html#00:10:12.160
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
accident, et cetera, they're pretty much immobile.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:17.200
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Terri Schiavo, you may have heard historically, she was a person here in the 90s in Florida.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:20.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Her heart stood still.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:26.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
She was reanimated.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:27.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And then for the next 14 years, she was what's called in a vegetative state.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:28.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So there are thousands of people in a vegetative state.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:31.760
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So they're, you know, they're, you know, they're like this.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:34.000
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Occasionally, they open their eyes for two, three, four, five, six, eight hours, and then
|
https://karpathy.ai/lexicap/0002-large.html#00:10:36.720
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
close their eyes.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:40.680
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
They have sleep wake cycle.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:41.680
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Occasionally, they have behaviors.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:42.680
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
They do like, you know, but there's no way that you can establish a lawful relationship
|
https://karpathy.ai/lexicap/0002-large.html#00:10:44.160
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
between what you say or the doctor says or the mom says and what the patient does.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:50.480
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So there isn't any behavior, yet in some of these people, there is still experience.
|
https://karpathy.ai/lexicap/0002-large.html#00:10:55.360
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You can design and build brain machine interfaces where you can see there's still experience
|
https://karpathy.ai/lexicap/0002-large.html#00:11:03.120
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
something.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:08.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And of course, these cases of locked in state, there's this famous book called The Diving
|
https://karpathy.ai/lexicap/0002-large.html#00:11:09.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Bell and the Butterfly, where you had an editor, a French editor, he had a stroke in the brainstem,
|
https://karpathy.ai/lexicap/0002-large.html#00:11:13.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
unable to move except his vertical eyes, eye movement.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:19.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
He could just move his eyes up and down.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:22.960
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And he dictated an entire book.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:25.280
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And some people even lose this at the end.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:27.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
All the evidence seems to suggest that they're still in there.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:30.320
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
In this case, you have no behavior, you have consciousness.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:33.360
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Second case is tonight, like all of us, you're going to go to sleep, close your eyes, you
|
https://karpathy.ai/lexicap/0002-large.html#00:11:37.520
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
go to sleep, you will wake up inside your sleeping body, and you will have conscious
|
https://karpathy.ai/lexicap/0002-large.html#00:11:41.880
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
experiences.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:46.520
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
They are different from everyday experience.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:47.520
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You might fly, you might not be surprised that you're flying, you might meet a long
|
https://karpathy.ai/lexicap/0002-large.html#00:11:49.840
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
dead pet, childhood dog, and you're not surprised that you're meeting them.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:53.520
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
But you have conscious experience of love, of hate, they can be very emotional.
|
https://karpathy.ai/lexicap/0002-large.html#00:11:58.280
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Your body during this state, typically it's REM state, sends an active signal to your
|
https://karpathy.ai/lexicap/0002-large.html#00:12:02.420
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
motor neurons to paralyze you.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:07.680
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
It's called atonia.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:09.360
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Because if you don't have that, like some patients, what do you do?
|
https://karpathy.ai/lexicap/0002-large.html#00:12:11.720
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You act out your dreams.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:14.220
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You get, for example, REM behavioral disorder, which is bad juju to get.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:15.660
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Okay.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:19.960
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Third case is pure experience.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:20.960
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So I recently had this, what some people call a mystical experience.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:22.760
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
I went to Singapore and went into a flotation tank.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:27.400
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Yeah.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:30.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
All right.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:31.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So this is a big tub filled with water, that's body temperature and Epsom salt.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:32.240
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You strip completely naked, you lie inside of it, you close the lid.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:37.800
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Darkness.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:41.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Complete darkness, soundproof.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:42.440
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
So very quickly, you become bodiless because you're floating and you're naked.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:44.920
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You have no rings, no watch, no nothing.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:48.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
You don't feel your body anymore.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:50.580
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
There's no sound, soundless.
|
https://karpathy.ai/lexicap/0002-large.html#00:12:52.880
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
There's no photon, sightless, timeless, because after a while, early on you actually hear
|
https://karpathy.ai/lexicap/0002-large.html#00:12:54.640
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
your heart, but then you sort of adapt to that and then sort of the passage of time
|
https://karpathy.ai/lexicap/0002-large.html#00:13:01.080
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
ceases.
|
https://karpathy.ai/lexicap/0002-large.html#00:13:06.600
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
Yeah.
|
https://karpathy.ai/lexicap/0002-large.html#00:13:07.600
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
And if you train yourself, like in a meditation, not to think, early on you think a lot.
|
https://karpathy.ai/lexicap/0002-large.html#00:13:08.600
|
Christof Koch: Consciousness | Lex Fridman Podcast #2
|
It's a little bit spooky.
|
