Sorry, I didn't mean to insult you. Also I didn't downvote your comment, someone else did.

What worries me is the incongruity of it all. What if Einstein, instead of working as a patent clerk and doing physics at the same time, chose to set up a Relativity Foundation to provide himself with money? What if this foundation went on for ten years without actually publishing novel rigorous results, only doing advocacy for the forthcoming theory that will revolutionize the physics world? This is just, uh...

A day job is actually the second recourse that comes to mind. The first recourse is working in academia. There's plenty of people there doing research in logic, probability, computation theory, game theory, decision theory or any other topic you consider important. Robin Hanson is in academia. Nick Bostrom is in academia. Why build SIAI?
