If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
Peter Thiel gave an AMA at Reddit, mentioned friendly AI and such (and even neoreaction :-D).
His answer to "Peter, what's the worst investment you've ever made? What lessons did you learn from it?" is intersting. He focuses on not investing more on facebook. The shift of focus says a lot about his mindset.
