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.
There's a great essay by Philip K. Dick (an excellent and important writer whom our reading list kind of grazes) about the purpose and meaning to be found in science fiction. He doesn't directly tackle issues of race and gender, but his interpretations of the purpose of science fiction are fascinating and complex.
