wow ngpio, this list is great. you've probably come across this one before as well but it's definitely a good one: "I don't know, Timmy, being God is a big responsibility"

Perhaps also check out his "Fine Structure" http://qntm.org/structure (different kind of thing, but it's good scifi..) and perhaps the ongoing series / work in progress "Ra" http://qntm.org/ra
I just read "Hell is the Absence of God". I just can't understand or relate at all to the "slave morality", as Nietzsche might put it, of that story, or wrap my head around why people choose to worship a creature roughly equivalent to the one imprisoned at the center of the galaxy in Star Trek V.
"Homer composed the Odyssey; given infinite time, with infinite circumstances and changes, it is impossible that the Odyssey should not be composed at least once. No one is someone; a single immortal man is all men. Like Cornelius Agrippa, I am god, hero, philosopher, demon, and world."
Honestly, just about all of Borges' fictions are really neat for the technically minded. Highly recommended!
