Elon Musk was just acknowledging Nick Bostroms paper
https://www.simulation-argument.com/simulation.pdfwhich, in itself does not state anything other than three mutually exclusive options (you have to choose one....unless you can think of another alternative)
In terms of this simulation/game, I think it is quite interesting, it generated you and me and this discussion, which beats minecraft hands down and suprisingly minecraft is popular.
I see little reason to run simulations of life, why not run simulations of an alternative or simplified life eg 3 dimensions space, one of time (US!....outside our simulation things may be incomprehensible, just adding one more dimension of space screws with your mind)
We can choose the many worlds interpretation or the Copenhagen interpretation. The latter with its associated experiments lends itself to the simulation hypothesis. It is constructed for us to perceive, that is why observation affects results.
