Re: enslaved - as Moravec put it:

I found the speculations absurdly anthropocentric. Here we have machines millions of times more intelligent, plentiful, fecund, and industrious than ourselves, evolving and planning circles around us. And every single one exists only to support us in luxury in our ponderous, glacial, antique bodies and dim witted minds. There is no hint in Drexler's discussion of the potential lost by keeping our creations so totally enslaved.
