On his university experience, in a discussion thread https://www.lesswrong.com/posts/MzfrRhB4Q7YgCW3f6/college-selection-advice#PuZtQ3excyvoPZh42 on LessWrong, March 2011
Context: Here's my experience. I applied to just MIT and my state university (University of Washington). I got on MIT's waiting list but was ultimately not accepted, so went to UW. I would certainly have gone to MIT had I been accepted, but my thinking now is that if I did that, I would not have had enough free time in college to write Crypto++ and think about anonymous protocols, Tegmark's multiverse, anthropic reasoning, etc., and these spare-time efforts have probably done more for my "career" than the MIT name or what I might have learned there.
