Those that think there is anything new in transumanism should read the 20th century arguments for eugenics, that is essentially what we're talking about albeit with a shiny new techno-hipster coating. This is not speeding up evolution, evolution encodes meaningful adaptations to an environment over eons, not fashionable "enhancements" to a persons "IQ"(however that happens to be measured) that may change from year to year. There is a holistic reality that is so blindly and eagerly thrown off by dreaming of the wonders of a brave post/transhuman future it makes one wonder at what point the post-posthumanists will circle back around and want to recover their true humanity unsullied by their forebears ham-handed tinkering. Good luck with all that, personally I'll stick with my boring old unmodified plain humanness.
