Future Dystopian Tech Wild Speculation

I changed the title of this thread because it's moving in a more fun direction. I figured the title should match.
Let's play a game. Make up a future technology that 1, is scientifically plausible but 2, you've stretched it about as far as you can imagine.
For example
Computers smarter than humans
1. Computers are always getting faster and more efficient. Although by some accounts, the fastest supercomputer has the equivalent intelligence of a slug, with Moore's law, in 18 months, that's as smart as 2 slugs, then 4, then 8, then 16, then 32, then. . . You get the idea. In sixty of those doublings you'd have a population of slugs that would cover the world six feet deep.
So I guess that's smart.
2. To stretch things as far as I can imagine, a computer would not only be smart enough to tell us we're wrong, there'd be no reason for humans to think anymore. It's like, how often do you offload your paperwork on your dog? (My dog ate it?) But we keep dogs around because we like them. I've got a turtle clunking around in a tank 4 feet from me, she's funny, and eats fish.
So our computers would make us nice homes where they could watch us, spay and neuter us to keep the population under control, give us nifty toys to destroy and feed us.
And yell at us when we miss the toilet.
Ok, it's your turn.
