Hmm that's a new one. I know of transhumarism but not anarcho-transhumanism. There isn't really much resource on there that concretly explains that philosophy. In general I support transhumanism in that we should attempt to improve our bodies and minds via technology. I'm guess anarcho-transhumanism is a combination of anarchism and transhumarism in which case I'd feel that's a bit... hmm, I feel regulations are important especially when modifying their bodies so if it is that combination than I'm generally gonna have to disagree. Though it's all a spectrum of course.
If you had super powers, what would you do with them?
