You ever hear of parsimony? The principle of parsimony is that the simplest explanation is most likely to be true. So, ask yourself, is it more likely that when you stub your toe you were clumsy and your body feels pain because that alerts you to damage and encourages you to be more careful, or that some vast AI engine somewhere is torturing another AI program (you), and that every aspect of reality is a fiction deliberately constructed for some reason, and that some whole actual reality also exists that hasn't been fabricated that this simulation is written in?

Yeah, naw. There's so much additional complexity necessary to try to make this a simulation of reality that it's vastly less likely than that what we see is what we get. Now, we are just clever monkeys that evolved the ability to guesstimate the trajectory of a rock thrown at fleeing prey well enough to usually eat of a day, so we don't have UV sight, or vast, planet sized brains to understand this big universe we are part of. We only have a little view of things and have to figure out the rest as best we can.

That's what makes it fun.

Thanks!
