This is a long, rambling, conversation (4 hours), so I have a hard time recommending the whole thing. I’d say that Wolfram and Yudkowsky do manage to find one another by the 4th hour (sections 6 & 7) and say some interesting things about computation and AI risk (much of the earlier conversation was on tangential matters). I note that the whole thing has been transcribed and there’s a Dropbox link for the conversation.
I will note that the conversation they did have was much better than what I had anticipated, which was a lot of talking past one another. And, yes, there was some of that, but as soon as that got going they worked hard at understanding what each was getting at.
Wolfram has some interesting remarks on computational irreducibility scattered throughout – that’s certainly one of his key concepts, and an important one. He also asserts, here …
