Like the video says. there is so much tech now, mostly coming from consumer side via gaming. Thats just the parts we see in public eye. There is SOOOO much more going on with things like FakeX and NAsaholes etc that it boggle the mind at time. Computer power and GFX capabilities just keep booming.
Ar some point it really will be impossible to tell whats what. See my other videos or search here for "faking" / nasa/spacex/fakex etc.
