One way that future robots could conquer the world is by violence. But that seems both inefficient and uncreative. Allow me to suggest some smarter ways for robots to do their conquering.
I start by imagining what happens when the first computer achieves what is called The Singularity. That's the moment the computer can program itself faster than humans can program it. Soon after that point, futurists say, you would see the computer rapidly evolve to have super intelligence and perhaps something that looks like free will. ...
...The computer doesn't need to be in a hurry, so it introduces Bitcoin and waits for it to evolve into the primary currency of the planet....

I don't believe the story I'm weaving. But I do think that the first signs of a benevolent post-singularity computer would include the following:
A mysterious digital currency with no known author.
Unusually well-behaved financial markets.
Slow and steady improvement in the economy.
Slow news days (lots of them)
Fewer military flare-ups
Stuxnet virus (unknown authors again)
Legalization of Marijuana (to keep humans happy)
I'm not saying the first post-singularity computer is already here. I'm just saying it looks that way.

At least Scott Adams has an active imagination.
