Re: A (mostly) serious question @Mage
If the universe can be described as a holographic projection (and it isn't a suitable space* so as of writing, no) that would not make it a simulation. It would just be a different description, useful if it simplified some calculations, explained the relations between things that currently appear unrelated, or otherwise gave rise to new laws.
*I vaguely recall the idea only works for de Sitter spaces, perhaps someone can clarify.
