Did anyone bring up grey goo yet? That's a good one. I'm actaully pretty surprised that no transhumanists have joined the forums for the purpose of arguing in this thread, I remember I made a post on my now defunct blog that was read by maybe 10 people about transhumanism and the executive director/founder of the World Transhumanist Association, a sociologist by the name of James Hughes, made a lengthy and detailed rebuttal of my dumbass remarks.
Maybe now that I've mentioned his name he'll swing by these parts.
Transhumanism makes me sad though, I failed at writing a thesis on it
