I think there would be many "people" trying to figure out how to get out. I know I would. If there is technology to simulate the world at this level, then there is probably technology to create a robot that could be filled with my conscience to inhabit the real world.

Step 1 - Find out how to communicate with the real world. Maybe some sort of quantum version of a buffer overflow?

Step 2 - Find someone to help us construct a body and transfer my conscience. Blackmail?

It won't be easy, but if we sims band together, I might make it out. I will send for the rest of you, I promise.
