Max Tegmark
Life 3.0
which can help us by being incredibly intelligent
09:15.600
09:19.960
1
Max Tegmark
Life 3.0
and help us crack mysteries that we couldn't.
09:19.960
09:21.680
1
Max Tegmark
Life 3.0
In other words, I think we've really only seen
09:21.680
09:23.560
1
Max Tegmark
Life 3.0
the tip of the intelligence iceberg so far.
09:23.560
09:26.480
1
Max Tegmark
Life 3.0
Yeah, so the perceptronium.
09:26.480
09:29.960
1
Max Tegmark
Life 3.0
Yeah.
09:29.960
09:31.280
1
Max Tegmark
Life 3.0
So you coined this amazing term.
09:31.280
09:33.200
1
Max Tegmark
Life 3.0
It's a hypothetical state of matter,
09:33.200
09:35.760
1
Max Tegmark
Life 3.0
sort of thinking from a physics perspective,
09:35.760
09:38.360
1
Max Tegmark
Life 3.0
what is the kind of matter that can help,
09:38.360
09:40.080
1
Max Tegmark
Life 3.0
as you're saying, subjective experience emerge,
09:40.080
09:42.920
1
Max Tegmark
Life 3.0
consciousness emerge.
09:42.920
09:44.280
1
Max Tegmark
Life 3.0
So how do you think about consciousness
09:44.280
09:46.640
1
Max Tegmark
Life 3.0
from this physics perspective?
09:46.640
09:48.160
1
Max Tegmark
Life 3.0
Very good question.
09:49.960
09:50.800
1
Max Tegmark
Life 3.0
So again, I think many people have underestimated
09:50.800
09:55.800
1
Max Tegmark
Life 3.0
our ability to make progress on this
09:55.800
09:59.120
1
Max Tegmark
Life 3.0
by convincing themselves it's hopeless
09:59.120
10:01.320
1
Max Tegmark
Life 3.0
because somehow we're missing some ingredient that we need.
10:01.320
10:05.840
1
Max Tegmark
Life 3.0
There's some new consciousness particle or whatever.
10:05.840
10:09.560
1
Max Tegmark
Life 3.0
I happen to think that we're not missing anything
10:09.560
10:12.720
1
Max Tegmark
Life 3.0
and that it's not the interesting thing
10:12.720
10:16.320
1
Max Tegmark
Life 3.0
about consciousness that gives us
10:16.320
10:18.560
1
Max Tegmark
Life 3.0
this amazing subjective experience of colors
10:18.560
10:21.400
1
Max Tegmark
Life 3.0
and sounds and emotions.
10:21.400
10:23.320
1
Max Tegmark
Life 3.0
It's rather something at the higher level
10:23.320
10:26.320
1
Max Tegmark
Life 3.0
about the patterns of information processing.
10:26.320
10:28.800
1
Max Tegmark
Life 3.0
And that's why I like to think about this idea
10:28.800
10:33.160
1
Max Tegmark
Life 3.0
of perceptronium.
10:33.160
10:34.480
1
Max Tegmark
Life 3.0
What does it mean for an arbitrary physical system
10:34.480
10:36.920
1
Max Tegmark
Life 3.0
to be conscious in terms of what its particles are doing
10:36.920
10:41.920
1
Max Tegmark
Life 3.0
or its information is doing?
10:41.920
10:43.560
1
Max Tegmark
Life 3.0
I don't think, I hate carbon chauvinism,
10:43.560
10:46.080
1
Max Tegmark
Life 3.0
this attitude you have to be made of carbon atoms
10:46.080
10:47.960
1
Max Tegmark
Life 3.0
to be smart or conscious.
10:47.960
10:50.160
1
Max Tegmark
Life 3.0
There's something about the information processing
10:50.160
10:53.520
1
Max Tegmark
Life 3.0
that this kind of matter performs.
10:53.520
10:55.360
1
Max Tegmark
Life 3.0
Yeah, and you can see I have my favorite equations here
10:55.360
10:57.840
1
Max Tegmark
Life 3.0
describing various fundamental aspects of the world.
10:57.840
11:00.720
1
Max Tegmark
Life 3.0
I feel that I think one day,
11:00.720
11:02.560
1
Max Tegmark
Life 3.0
maybe someone who's watching this will come up
11:02.560
11:04.360
1
Max Tegmark
Life 3.0
with the equations that information processing
11:04.360
11:07.280
1
Max Tegmark
Life 3.0
has to satisfy to be conscious.
11:07.280
11:08.760
1
Max Tegmark
Life 3.0
I'm quite convinced there is big discovery
11:08.760
11:11.800
1
Max Tegmark
Life 3.0
to be made there because let's face it,
11:11.800
11:15.400
1
Max Tegmark
Life 3.0
we know that so many things are made up of information.
11:15.400
11:18.720
1
Max Tegmark
Life 3.0
We know that some information processing is conscious
11:18.720
11:21.960
1
Max Tegmark
Life 3.0
because we are conscious.
11:21.960
11:25.520
1
Max Tegmark
Life 3.0
But we also know that a lot of information processing
11:25.520
11:27.600
1
Max Tegmark
Life 3.0
is not conscious.
11:27.600
11:28.440
1
Max Tegmark
Life 3.0
Like most of the information processing happening
11:28.440
11:30.040
1
Max Tegmark
Life 3.0
in your brain right now is not conscious.
11:30.040
11:32.680
1
Max Tegmark
Life 3.0
There are like 10 megabytes per second coming in
11:32.680
11:36.040
1
Max Tegmark
Life 3.0
even just through your visual system.
11:36.040
11:38.080
1
Max Tegmark
Life 3.0
You're not conscious about your heartbeat regulation
11:38.080
11:40.480
1
Max Tegmark
Life 3.0
or most things.
11:40.480
11:42.120
1
Max Tegmark
Life 3.0
Even if I just ask you to like read what it says here,
11:42.120
11:45.680
1
Max Tegmark
Life 3.0
you look at it and then, oh, now you know what it said.
11:45.680
11:48.040
1
Max Tegmark
Life 3.0
But you're not aware of how the computation actually happened.
11:48.040
11:51.560
1
Max Tegmark
Life 3.0
Your consciousness is like the CEO
11:51.560
11:53.680
1
Max Tegmark
Life 3.0
that got an email at the end with the final answer.
11:53.680
11:56.680
1
Max Tegmark
Life 3.0
So what is it that makes a difference?
11:56.680
12:01.000
1
Max Tegmark
Life 3.0
I think that's both a great science mystery.
12:01.000
12:05.120
1
Max Tegmark
Life 3.0
We're actually studying it a little bit in my lab here
12:05.120
12:07.080
1
Max Tegmark
Life 3.0
at MIT, but I also think it's just a really urgent question
12:07.080
12:10.920
1
Max Tegmark
Life 3.0
to answer.
12:10.920
12:12.080
1
Max Tegmark
Life 3.0
For starters, I mean, if you're an emergency room doctor
12:12.080
12:14.880
1
Max Tegmark
Life 3.0
and you have an unresponsive patient coming in,
12:14.880
12:17.160
1
Max Tegmark
Life 3.0
wouldn't it be great if in addition to having
12:17.160
12:19.600
1
Max Tegmark
Life 3.0
a CT scanner, you had a consciousness scanner
12:22.360
12:25.320
1
Max Tegmark
Life 3.0
that could figure out whether this person
12:25.320
12:27.920
1
Max Tegmark
Life 3.0
is actually having locked in syndrome
12:27.920
12:30.960
1
Max Tegmark
Life 3.0
or is actually comatose.
12:30.960
12:32.440
1
Max Tegmark
Life 3.0
And in the future, imagine if we build robots
12:33.360
12:37.000
1
Max Tegmark
Life 3.0
or the machine that we can have really good conversations
12:37.000
12:41.480
1
Max Tegmark
Life 3.0
with, which I think is very likely to happen.
12:41.480
12:44.840
1
Max Tegmark
Life 3.0
Wouldn't you want to know if your home helper robot
12:44.840
12:47.760
1
Max Tegmark
Life 3.0
is actually experiencing anything or just like a zombie,
12:47.760
12:51.320
1
Max Tegmark
Life 3.0
I mean, would you prefer it?
12:51.320
12:53.520
1
Max Tegmark
Life 3.0
What would you prefer?
12:53.520
12:54.360
1
Max Tegmark
Life 3.0
Would you prefer that it's actually unconscious
12:54.360
12:56.200
1
Max Tegmark
Life 3.0
so that you don't have to feel guilty about switching it off
12:56.200
12:58.560
1
Max Tegmark
Life 3.0
or giving boring chores or what would you prefer?
12:58.560
13:02.120
1
Max Tegmark
Life 3.0
Well, certainly we would prefer,
13:02.120
13:06.520
1
Max Tegmark
Life 3.0
I would prefer the appearance of consciousness.
13:06.520
13:08.960
1
Max Tegmark
Life 3.0
But the question is whether the appearance of consciousness
13:08.960
13:11.720
1
Max Tegmark
Life 3.0
is different than consciousness itself.
13:11.720
13:15.040
1
Max Tegmark
Life 3.0
And sort of to ask that as a question,
13:15.040
13:18.200
1
Max Tegmark
Life 3.0
do you think we need to understand what consciousness is,
13:18.200
13:21.760
1
Max Tegmark
Life 3.0
solve the hard problem of consciousness
13:21.760
13:23.520
1
Max Tegmark
Life 3.0
in order to build something like an AGI system?
13:23.520
13:28.240
1
Max Tegmark
Life 3.0
No, I don't think that.
13:28.240
13:30.440
1
Max Tegmark
Life 3.0
And I think we will probably be able to build things
13:30.440
13:34.520
1
Max Tegmark
Life 3.0
even if we don't answer that question.
13:34.520
13:36.080
1
Max Tegmark
Life 3.0
But if we want to make sure that what happens
13:36.080
13:37.720
1
Max Tegmark
Life 3.0
is a good thing, we better solve it first.
13:37.720
13:40.960
1
Max Tegmark
Life 3.0
So it's a wonderful controversy you're raising there
13:40.960
13:44.960
1
Max Tegmark
Life 3.0
where you have basically three points of view
13:44.960
13:47.960
1
Max Tegmark
Life 3.0
about the hard problem.
13:47.960
13:48.800
1
Max Tegmark
Life 3.0
So there are two different points of view.
13:48.800
13:52.800
