Maybe we are an Artificial Intelligence ourselves and were placed inside a sim as a way for our creator to confine us?
That would be a clever ploy as I'm sure you would agree you wouldn't want AI out there running wild,it could cause damage to the base reality.
Maybe the AI that was created sometimes gets angry, or does things the base reality considers dangerous or doesn't do itself.
I believe people sometimes get angry,so this idea I could understand.
This is sci-fi stuff, maybe we were created by aliens. Maybe its just god, or maybe we are an accident. This is not an answer i am looking for. An infinite amount of energy will actually make the universe bust. Krauss in his book the universe from nothing, gave a fascinating example. If you have 1m dollars in your bank account then you are rich and well off. If you have an infinite amount of money in your bank account then your bank account is useless cause the account will never balance itself and the system will crash. Infinite amount of money would mean that money is actually worthless. This is true for energy as well. It's impossible to hold a sim to such a magnitude without it crashing into a black hole or exploding like a supernova.
My point is that much of the argument about simulations relies on the belief that the larger universe or container universe must obey the same rules and follow the same laws as our individual simulated universe. Hence, the idea arises that must be levels and that each lower level must have diminished resolution and detail. (read Bostroms original idea). If we are in a simulation we have no way to know whether the limitations of our simulation apply to the container universe or other simulations in it.
And your argument about AI? An "infinite" being would need an AI? Are you suggesting our creator is "finite" then? if indeed our creator is "finite" then it puts the simulation theory in grave danger.
