Just in case there are new readers, I want to refer them to the writings of Dale Carrico, probably the best transhumanist critic thus far. He's a lecturer at Berkeley. (Maybe The New Atlantis should try hiring him, though I sort of doubt they'd get along.) I especially enjoy this post responding to my "Transhumanism Has Already Won" post:
The Robot Cultists Have Won?
When did that happen?
In something of a surprise move, Singularitarian Transhumanist Robot Cultist Michael Anissimov has declared victory. Apparently, the superlative futurologists have "won." The Robot Cult, it would seem, has prevailed over the ends of the earth.
Usually, when palpable losers declare victory in this manner, the declaration is followed by an exit, either graceful or grumbling, from the stage. But I suspect we will not be so lucky when it comes to Anissimov and his fellow victorious would-be techno-transcendentalizers.
Neither can we expect them "to take their toys and go home," as is usual in such scenes. After all, none of their toys -- none of their shiny robot bodies, none of their sentient devices, none of their immortality pills, none of their immersive holodecks, none of their desktop nanofactories, none of their utility fogs, none of their comic book body or brain enhancement packages, none of their kindly or vengeful superintelligent postbiological Robot Gods -- none of them exist now for them to go home with any more than they ever did, they exist only as they always have done, as wish-fulfillment fancies in their own minds.
