I am a transhumanist. Before you start making fun of me, read more of Michael Anissimov's blog Accelerating Future. Singularity, life extension, friendly artificial intelligence, nanotechnology, existential risk: he excels at introducing these concepts and arguing cultural or technological issues they raise. As a fund raiser for the Singularity Institute for Artificial Intelligence, he knows what he writes about and gives many pointers to the articles of the best futurologists out there.
And he is very smart and masters the art of providing calm thoughtful answers to low and mean attacks from anti-transhumanist journalists and bloggers. Read those answers and make up your mind: this future he discusses is not so far ahead, this is important stuff, what do you believe in?
