That idea also comes back in Diaspora. That book contains some nice things, like mind-grafts, procreation/creation in a non-biological society etc. Loved that book. I also like Ted Chiangs books. I.e. the idea from story of your life (a language that treats time flow differently), also "Understand" [0] is nice: What happens we we actually increase our thinking capacity. I mean that is hard to comprehend without a nice story, for a puny brain like mine.
