Thanks, this is the kind of informed (I believe in Hansons case) contrarian third party opinions about main isuess that I perceive to be missing.

Surely I could have found out about this myself. But if I was going to wait until I first finished my studies of the basics, i.e. catch up on formal education, then read the relevant background information and afterwards all of LW, I could as well not donate to the SIAI at all for the next half decade.

Where is the summary that is available for other issues like climate change. The Talk.origins of existential risks, especially superhuman AI?
