David Deutsch - AI, America, Fun, & Bayes

  Okay, today I'm speaking with David Deusch.

• 00:07

  Now this is a conversation that I've been eagerly wanting to have for years.

• 00:12

  So this is very exciting for me.

• 00:14

  So first let's talk about AI.

• 00:16

  Can you briefly explain why you anticipate that AIs will be no more fundamentally intelligent than humans?

• 00:24

  I suppose you mean AGI's.

• 00:27

  Yes.

• 00:29

  And by fundamentally intelligent,

• 00:32

  I suppose you mean capable of all the same types of cognition as humans are in principle.

• 00:42

  So that would include doing science and doing art and in principle also falling in love and being good and being evil and all that.

• 00:58

  So the reason it, the reason is twofold and one half is about computation hardware,

• 01:10

  computation hardware, and the other is about software.

• 01:15

  So if we take the hardware, we know that our brains are Turing complete.

• 01:26

  bits of hardware and therefore can exhibit the functionality of running any computable function program for any computable function.

• 01:40

  Now, when I say any, I don't really mean any because you and I sitting here,

• 01:48

  we're having conversation and we could say, we could have any conversation.

• 01:51

  Well,

• 01:54

  We can assume that maybe in a hundred years time we'll both be dead and therefore the number of conversations we could have is strictly limited.

• 02:05

  And also some conversations depend on speed of computation.

• 02:12

  So, you know, if we're going to be solving the traveling salesman problem.
