After watching the video in the OP, I think the strongest argument for myself was the clip at the very end. I 100% believe all of the following:
1) Consciousness is a result of data being processed (i.e. our brain processes data input in the form of sight, smell, touch, taste, sound, etc.)
2) There is nothing magical about our brain, and at some point we will be able to reproduce exactly what it does in the form of a computer.
3) At that point, we will essentially be able to create consciousness "from nothing." That is to say, we will be able to run simulations of life in general.
4) Those simulations we create will be "virtual" universes, and there will be "people" in those universes that are "conscious" and unaware that they are part of a simulation.
5) At that point, since the number of simulated universes will greatly outnumber real life (like the guy in the video said), it's extremely unlikely that we are real.
Fuck my life...
Actually, this is sort of awesome. If you believe that theory, it could lead to a better life because you know this is "just a simulation." Carpe fucking diem!
Somebody correct me if I've left a gap in my logic, or if one of those points are invalid. The only way to invalidate it, that I can forsee, are arguments of religion (i.e. that our brain/existence *IS* "magical").
I now seem to have given myself only two possible outlooks on life: religion or simulation (and I've considered myself agnostic for years)
EDIT: The only thing holding me up from fully believing we are a simulation is that if time and space (the *real* time/space, assuming there is one -- otherwise this whole thought process is pointless) are infinite, then there are also infinite "real" universes. If there are infinite real universes and infinite simulated universes, then which is more likely that we are part of? Is it an equal chance?
