Hardware technical difficulties experienced at the end of the game (spoilers)

[Mudbill]

I guess the more correct term would be virtual simulation or emulation.

Say that the simulations are sandboxed. They have a specific amount of resources dedicated to them, and that's it. If they exceed it (or close up to rather), they will only hurt themselves, not the host computer.

The live personalities are also simulations, but they aren't sandboxed, so if they wanted to, they could consume all available resources.
