The idea that we live in a computerized simulation seems a bit myopic to me because when you really think about it deeply, a computer is made of atoms.
So if this universe we're in is a computer, then that computer is made of atoms and exists in a higher reality, which means that higher reality isn't a computer. And if you just say that it is a computer, then the same logic applies again, because there would be a higher reality above that one that isn't a computer.
Eventually, it isn't a computer, so I don't think the digital simulation hypothesis is correct. It's just a sign of the times, because computers are finally here.
First people said reality was a book, and then they said it was a wheel, and now they say it's a computer. It's all culture.
Reality is something much more indescribable and special than digital ones and zeros.
