Sometimes I wonder what it’d be like to live in simulated universe.

Only tangentially related, but the lovely (quite) short story "I don't know, Timmy, being God is a big responsibility" is fantastic and kind of hits on simulating worlds, in a sense:

You say that as if you aren't. What proof do you have either way?

Pretty sure all of you are in my simulation... Right? Or maybe I'm just in a coma and this is a coma dream...

does anybody know what the music accompanying the full video was? It seemed familiar but I couldn't place it. Maybe AI generated?

It sounds an awful lot like "Maiden Voyage" (the instrumental version) by the clockwork dolls, but not quite.

When thinking about this one, I always wonder if it even matters.. playing both "Yes" and "No" scenarios doesn't really offer any insight for me. Maybe it's a degree of nihilism but it makes me not get overwhelmed.
