Elon Musk:
"Given that we’re clearly on a trajectory to have games that are indistinguishable from reality and those games could be played on any set top box or any PC, and their would probably be billions of computer or set top boxes, it would seem to follow that the odds we are in base reality are one in billions."
Its incredibly hard to comprehend, especially if you dont have a grasp of probability or if you have strong beliefs.
Personaly base reality or not we may as well enjoy the ride.
