David Pearce was still taking questions as of an hour ago. He gave me a much more thorough answer to my question than I have gotten in the two other AMA's I submitted questions to. Neil Strauss and the Atlantic writer whose name slips me at the moment both gave me terrible drive by answers with about two seconds of thought behind them.
Transhumanist philosopher David Pearce co-founded Humanity+ with Nick Bostrom.
He is currently answering questions in an AMA on reddit/r/transhumanism.
