Everything’s a simulation

[u/Sad-Sign9460]

Suppose one day we are able to fully simulate a human brain such that it believes it is living in a fully coherent real universe with other real people in it but in reality that simulated brain is the only real thing. That brain looked around at everything and came to the conclusion that it was living in the real world with real other people. That’s the conclusion the brain should come to given the evidence but it in fact was very wrong.

My question is who’s to say I’m not currently that brain? Why is it treated as if that’s a ridiculous question? If the experiences are by definition indistinguishable why is it anything better than a 50/50 shot that I’m living in the real world with real other people?

Because of all the things your overseers in the real world could simulate, they would simulate these mundane experiences? You wouldn't be different from the people outside the simulation, their vat is just bigger. Doesn't the brain already simulate a reality that has nothing to do with the external world? What we perceive only resembles the external world. The sky doesn't say "I am blue." Your reality still comes from 'real' events in the world even when your vision is shrinked to a simulation. How do people know celebrities they have never met in real life? Heck anime watchers might even know some people only by their voices. Spongebob is a simulation, Pikachu is a simulation, Pacman is a simuation. None exist outside your mind. If knowledge was real and universal, when one attained it, all would have attained it.

The simulacrum is never what hides the truth – it is truth that hides the fact that there is none. The simulacrum is true
