I’ve thought about it for a while.. During the video my mind was forming counterarguments, and the more you think about it, the more you see that they actually pulled together a lot of big assumptions from all sorts of different areas to arrive at this conclusion… It doesn’t make that much sense as the video wants you to believe.
Computers processing speeds have been stagnating for a while now. I don’t rule out the possibility that somewhere we’ll meet a physical barrier (in terms of materials, heat produced, or whatever) and that we cannot have an infite amount of processing speed. Plus I highly doubt whether computers would ever be ALLOWED so powerful that they would be able to create me, you, us, and our consciousness. This is highly endangering for human life, we’ve all seen the Matrix… However, I do agree that computers might once be powerful enough to create seemingly real environments.
But then; what IF there was this advanced civilisation? Why on earth would they bother with building models of history? Wouldn’t it be far more interesting to just build models of the present and simulate these extra fast to gain future-sight? Honestly, I can’t see why me going to the toilet would be interesting for some advanced civilization. You could say it’s because of determinism; every small action has it’s influence and is meaningful. But then, if those ancient people would start running around in it, they would screw up everything. THEIR original history would be gone and instead be altered in several dimensions. If they’d really want to learn from the past, they’d know this is not the way. However, I do like this notion of ‘time-traveling’. It’s one of the more plausible ways.
Or maybe they just want to have fun in a virtual reality which does not resemble their past.. In that case, they’re just immoral, unethical asses, because of all the suffering, pain, war,torture and unhappiness which they make us go through (for no particalur reason but their own gain/fun). The ancient people would be the gods, laughing at us while eating popcorn.
There was more but I kind of forgot. I think it’s bullshit. Either that, OR the system is preventing us all from finding out by creating scepticists
