If we're living in a computer simulation like in The Matrix, how would we know? It might be really hard to tell, according to philosophers and physicists.
It seems some leaders in Silicon Valley are taking the possibility seriously. At least two tech billionaires are recruiting scientists and funding research on a way to break us out of "the Matrix" that we may or may not be living inside of, according to a recent New Yorker profile of Sam Altman.
"Many people in Silicon Valley have become obsessed with the simulation hypothesis, the argument that what we experience as reality is in fact fabricated in a computer," Tad Friend wrote in the New Yorker piece. "Two tech billionaires have gone so far as to secretly engage scientists to work on breaking us out of the simulation."
