Well, if this approach fascinates you (it repels me) you'll probably enjoy
Greg Bear's new novel Slant. He even cites Extropians by name as respected
in one respect by the group in the book that thinks along the lines you're
suggesting. (I know you're not necessarily advocating these means.) There
will be a review of Slant in Extropy Online very soon.
