Its such a philosophical dead end. I know a few people who really want the world to be a simulation but I cant understand why. I think they want an excuse to have nothing matter and be shitty.
But i would not live my life any differently if we found out that this is a simulation. Because its still real to me and there's no reason to believe I can exist outside the simulation any more than my sims can exist outside the game.
To be completely cynical: they'd blame the jews for hiding this knowledge from them and use it, generally, to sow distrust in the institutions we already have for supporting "non-simulation theory". (see: flat earth)
Well, he constantly wears what I can only describe as an attempt to make a power armor straight from a 2000s live action sci-fi, constantly screams that everyone is dumb and that "The Great Observer" will free believers from this simulation, believes that if he remains hidden for a couple of minutes, police will simply lose him like this was GTA, and other dumb shit.
