A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

I actually study physics :D
that's partly why I care about making the distinction between science and non-science. To be scientific, a theory needs to be, first and foremost, falsifiable. That sounds counterintuitive, but you need to propose experiments that could prove you wrong. And then if they fail, you got a good indication you might be on to something.
A (good enough, as you said) simulation is per definition unfalsifiable. It's also a wild assumption that "the real world" obeys the same laws of physics ours does, and I consider any statistical argument based on that assumption to be pretty unconvincing.
Ultimately, the simulation theory is a nice thought experiment and a great setpiece for sci-fi, but not much more. It's kinda similar to the many worlds interpretation of quantum mechanics, actually. Cool to think about, not at all relevant for us.
Thought experiments, while useless for direct science, are an excellent tool for mental processing. It can often lead to falsifiable experiments, that helps tease out the nature of reality.
The amount of good science that comes out of stupid "what if" type games/discussions/thought experiments would unnerve many people. The catch is that it needs to be backed up by old fashioned slog work.
As for the many worlds Vs Copenhagen interpretation, in most ways they are impossible to separate, they look at the same data, and create the same conclusion. There are still cracks that can be pried at, however. Most will lead to nothing, a few can help understand QM better, and find its flaws. Ultimately, however, the maths and measurements win. Any understanding method must conform to those. The model just helps envisage future paths.
Exactly! I'm by no means against these thought experiments, I think they're super interesting and might lead to new insights down the road. I'm just irked out by people staying these things as fact, using Elon Musk level popscience arguments.
