Look, when the matrix came out, there were a lot of people who thought we were in the matrix. It was a big todo until eventually most people just grew out of it.

Think about it this way - either we are in a simulation and we just will never know, so it's effectively a useless train of thought - or we aren't, and it's not a useful train of thought.

I recommend trying to ground yourself in the material understanding of the world, using occams razor in situations like this, and focusing on the future we could build, instead of the solipsistic path you're walking down.
