Only one robot?

That's like when people thought having a computer for every person was outrageous.

You'll have dozens of robots. Like you have dozens of computers.

Sometime in the 69s or 70s one of those futurist guys wrote something like "in the future you will have so many computers you'll throw them out because you just don't need them. They'll be in your boxes of breakfast cereal." and you know what, they're in greeting cards. They're sometimes even in your breakfast cereal. The computer in your mouse that lets it talk USB is more powerful than any desktop computer in the '70s or early '80s.

Robots are going to go the same way.

But they're not going to be your plastic pal who's fun to be with, humanoid robots. They're going to be roombas, and dog walkers, and washing machines, and they kind of already are with your internet of things oven that sends bluetooth messages to your cellphone when it thinks it needs to be cleaned. Except it'll be sending those messages to a cleaning robot.

You won't even think of them as robots, like you don't think of the desktop-class computer in your optical mouse (which actually has two desktop class computers if you count the DSP that does the motion tracking) as a computer.
