Just the complexity of all the things that happen in the world and individual lives when I’m not looking is enough to do that for me. Like, if I smashed in the door of any random house I would find new and different furniture and random strangers doing whatever it is they’re doing at that time of day because everybody is living individual lives. Sure, I could be hallucinating that too, but really I do not think I am creative enough. I’ve also worked in multiple positions that had more opportunity than most to peer behind the curtains into people’s private lives to the point where I easily accept that life is happening all over the place.

The shared simulation is much more plausible to me than me existing in an individual universe. I don’t really think it’s true either but that’s more of a bias.
