I find it highly unlikely that we live in a simulation. Anyone who has implemented any kind of simulation has found out that they are hugely wasteful. It requires a huge amount of complexity to simulate even a tiny, low-complexity world. Therefore, all simulations will try to optimize as much as possible. However, we clearly don’t live in a tiny, low-complexity, optimized world. Our everyday experiences could be implemented with a much, much lower-complexity world that doesn’t have stuff like relativity and quantum gravity and dark energy and muons.
The basic premise that simulations are basically the same as reality, and that there many simulations, but only one reality, and that statistically, we therefore almost certainly live in a simulation, is not consistent with my experience working on simulations. Any simulation anyone builds in the real world will by necessity be infinitely less complex than actual reality, and thus infinitely less likely to contain complex beings.
