Guess that depends wether one defines 'simulation' as technical in nature, or as "being" for lack of a better term.
Nevertheless, it is a nice hack for not worrying too much about potential dystopias, if one has enough unique evidence for life on Earth already being "multidimensional", to use a somewhat dated model.
I see these views do not get much sincere attention in the general discourse, so your video will be helpful in that regard.
ahhhh nice point. Simulation doesn't have to be mechanical. That leaves room for both to be true.
If we think about our concept of time things change. Non linear time leaves space for all we know to be like some kind of simulation. Or alternate dimensions also have the same effect.
That's probably more along the lines of what he meant as simulation. It's just an alternate reality taking place in our heads
