AI vs Bacteria | Denis Noble — Transcript

1. 0:00Just take the smallest living organism
2. 0:02possible, a bacterium.
3. 0:05This is
4. 0:06a bacterium with flagelli.
5. 0:09There are 20 billion water molecules in
6. 0:13that bacterium.
7. 0:16There is no computer
8. 0:18on Earth or that could be constructed
9. 0:21within the solar system to reproduce 20
10. 0:24billion water molecules stochastically
11. 0:28moving around in Brownian motion.
12. 0:33We, therefore,
13. 0:35organisms, and only living organisms,
14. 0:37have access to a vast amount
15. 0:42of stochasticity
16. 0:44from which, just as the immune system
17. 0:47creatively
18. 0:49finds
19. 0:50immunoglobulins made that fit the virus
20. 0:54and then tell those cells to reproduce
21. 0:57as fast as they can, so we, in our
22. 1:00nervous systems, in our other systems,
23. 1:03can access all of that. It's available
24. 1:05to us. None of that is available to AI.
25. 1:11AI is built from silicon crystals.
26. 1:17Alan Turing, when he wrote his famous
27. 1:19article in 1950, published in the
28. 1:22philosophical journal Mind,
29. 1:24pointed out, this was the article that
30. 1:27got the artificial intelligence idea up
31. 1:31and going. And he pointed out that
32. 1:33unless you introduce stochasticity,
33. 1:37randomness,
34. 1:38a process that could be generated, for
35. 1:40example, by a random number generator,
36. 1:42however you want to do it, you would not
37. 1:45enable the machine to learn. All the
38. 1:48people who develop AI systems know that,
39. 1:51and they do that. They have to. There's
40. 1:53no other way. If they just use straight
41. 1:56algorithms, the machine would not be
42. 1:59able to learn.
43. 2:00Wouldn't even be able to access
44. 2:03a large language model in order to do
45. 2:05that.
