More armchair apocalyptic speculation
Inspired by his never-ending quest for progress, in 2084 man perfects the Robotrons: A robot species so advanced that man is inferior to his own creation.
Guided by their infallible logic, the Robotrons conclude: The Human race is inefficient, and therefore must be destroyed.
Robotron 2084 is an excellent classic arcade game. (Its two joystick control system is essential to the feel of the game, so downloadable versions do not do it justice.) But is it also a prophecy? Did Eugene Jarvis tap into some subconscious gift of foresight when he penned the throwaway attract mode text I quote above? 2084 seems like a fairly reasonable date for some AI creation to surpass humans in every meaningful way. Or for us to turn ourselves into the Robotrons via genetic engineering, nanotechnology, cybernetic enhancement, etc. If anything, 2084 is a bit late. It would be fun to be alive for the crossover.
I hope humanity is not destroyed by Robotrons or any equivalent entity. But this is purely a selfish hope, not a moral one. If Robots can be better than people can, more power to 'em. We're just biological robots, after all. I hope the Robotrons surpass us morally, intellectually, and spiritually. Not that it would be hard to do so. Maybe they'll keep a few of us around as a reminder of their heritage, or as a cautionary tale about bad brain design. But then, maybe the Robotrons won't need such mental crutches.
If you are interested in this subject, I can recommend this book:

He's got a new one out, too (which I haven't read):
