Science

The simulation "hypothesis" is so infantile it beggars belief. People vastly overestimate what computers can actually do, because they've become good at producing visual illusions. But if you look at the vast amount of data needed to simulate - or even capture faithfully - even very modest systems, it's clear that even all the computing power on the planet today barely scratches the surface.

I also find it insane the way "experts" claim that it is "more likely than not" that we live in a simulation based on nothing more than some highly questionable assumptions about what is even possible, let alone likely.

I would suggest that the most computationally efficient way to simulate a universe is with the universe itself.
