There has been no space collonization organization there. No space elevator team either. And what about the FHI? Just wondering.
Surely those who have been there incorporate all of the above. And the SIAI does incorporate all of those who have been there, after all a superhuman AGI can solve all those other problems? But if you disregard fooming AI for a second, then I'd rather put my money with some more specific objective. Space elevator research seems to be very promising example here. A well-constrained problem with clear payoffs (x-risk mitigation through space colonization, new frontiers for resources etc.).
It's not clear how your comment relates to the talk.
A week ago I made a pitch for the Singularity Institute to a crowd of interested potential donors, along with a number of leaders of other non-profit organizations with relatively radical and innovative goals. The videos are here, and should be a good introduction to a significant part of the noosphere for people not yet familiar with it.
