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.
https://karpathy.ai/lexicap/0002-large.html#00:13:12.560
