Why does it matter? Not trying to dismiss, but truly, what would it mean to you if you could somehow verify the "simulation"?

If it would mean something drastic to you, I would be very curious to hear your preexisting existential beliefs/commitments.

People say this sometimes and its kind of slowly revealed to me that its just a new kind of geocentrism: its not just a simulation people have in mind, but one where earth/humans are centered, and the rest of the universe is just for the benefit of "our" part of the simulation.

Which is a fine theory I guess, but is also just essentially wanting God to exist with extra steps!
