Post-Humanity in space

Hi all, for an interesting take of post humanity in space, read Bruce
Sterling's

novel SCHISMATRIX. There are two big factions: Shapers (genetically enhanced)
and Mechanist

(prosthetic gerontocracy), some older colonies orbiting the Moon, now in

decline, and several other (very odd) splinter groups. The question echoing in
the background is: "what is human and what is no

longer human?".

Have fun :-)

Ciao,
