So. There is a comic, bohemian drive, which looks at the solar system after the last human has died (peacefully) and robots inhabit the nine planets, various moons, and asteroids. The structure of the pages within the site is a bit odd, don't expect it to update anytime soon, but it's only 75 episodes, so finite procrastination, and it's an interesting society that is created. Also interesting commentary on humanity.
The site also links to ask philosophers, which addresses many questions that we've dealt with, sometimes peripherally, in class. I don't necessarily agree with what they say, but it's well-articulated food for thought.
