The content of John Baez's This Week's Finds: Week 310:
Includes
- Discussion of global warming and geoengineering.
- A reference to a paper by David Wolpert and Gregory Benford on Newcomb's paradox
Note: The upcoming This Week's Finds: Week 311 is an interview with Eliezer Yudkowsky by John Baez.
Since XiXiDu also asked this question on my blog, I answered over there.
I have read most of those things, and indeed I've been interested in AI and the possibility of a singularity at least since college (say, 1980). That's why I interviewed Yudkowsky.
