I think if you take a kind of birds-eye view (i.e. The proverbial forest) of the world around us without putting effort into understanding the granular nature of the individual things (i.e. the trees) around us, then one of the takeaways could be that we exist in an otherwise chaotic universe, which might give rise to this thought that we're living in a simulation. βThat said, the world isn't chaotic, not really. It is an incredibly complex group of relations and things, and most of it has little concern for us as individuals.
Some of us sometimes struggle to see the forest from trees. Others of us sometimes struggle to see the trees from the forest.
There's a big ol' beautiful world out there beyond our computers and the games we play. It's worth going out and studying a lot of it.
-What would be the implications if we were in a simulation? would it matter?
