The Timeline says that by 4000 computers will reach their pinnacle in development.
Meaning that, by that point, not only will we be god-like posthuman badasses, it will also be possible to run perfect simulations of the universe.
Just think, entire universes blinking in and out of existence to us on a computational substrate, while to the test subjects billions of years pass!
Mind-blowing stuff to think about.
When I first read the prediction for 4000 CE I was just kind of like, "meh", but then this thought just dawned on me.
