Dilbert: I created a simulated world made entirely of software. I programmed all of the people in the simulation to think they are real people with free will.
Dogbert: Are they sentient beings?
Dilbert: They think they are.
Dogbert: What if they discover their true nature?
Dilbert: I programmed limits into their physics so they can never observe the walls of their reality. For example, they can't get to the edge of their universe because they can't exceed the speed of light. And they can't find out what they are made of because, to them, it looks like probability at the quantum level.
Dogbert: Wouldn't those limits tip of the smart ones?
Dilbert: I coded them to not trust smart people.
