I don't think that we're in a simulation, but I do find myself occasionally entertaining the idea of it.
I think it would be kinda funny, because I have seen so much ridiculous shit in my life, that the idea that all those ridiculous things were simulated inside a computer or that maybe an external player did those things that I witnessed, is just too weird and funny at the same time lol.
Also, I play Civilizations VI and I occasionally wonder 'What if those settlers / soldiers / units / whatever are actually conscious. What if those lines of code actually think that they're alive?'. In that case, they are in a simulation. The same could apply to other life simulators, such as the Sims 4.
Idk, what does Lemmy think about it?
It doesn't matter in the end.
