Right, that. Is it not meant as an answer to the question of how we know? That’s how it seemed to me in the podcast.

(It's really the only theory of knowledge we have.) From your article, I don't see @yudapearl adding anything of value to Popperian epistemology, nor criticizing it. Both are welcome. Again, I may change my mind if I read the book.

@bnielson01 @yudapearl @onnlucky @ks445599 @SamHarrisOrg

I skimmed it. The touch point I see between the two is the focus on causation. And the criticism of deep learning is correct. The reason Popperians tend to have an attitude of "all or nothing" is because it's the best theory of knowledge we have.

We then came up with tests for each of them by selectively turning off WiFi, cellular, and bluetooth on both phones. Bluetooth survived the selection process as the best guess.

An unbounded general purpose problem solver would be an AGI. I guess that error correction is a requirement for being unbounded. So “no” to the second part of your question: that would violate AGI’s universality.

Present day computer programs are pessimistic: they are written to perform a specific purpose, and then terminate. They cannot keep going in an unbounded fashion or correct errors the programmer made. They are designed to oppose unbounded progress.

Error correction on a software level, yes. The brain's architecture doesn't matter though, see episode 03. For it to matter, it would need to violate computational universality. soundcloud.com/dchacke/artifi…

If you insist however, IIRC Popper took Tarsky’s definition of truth (= correspondence to facts) and amended it a little by saying that whatever is part of a true theory should be considered real. Would need to check the source though, probably also somewhere in C&R.
