the Evil people who rule our world would use the advancements of cybernetics to turn earth into New-Phrexia
they'd turn us all into hideous horrible monstrosities that live only to spread their hate and send us out through the cosmos and dimensions over eons simply because they have a bottomless and limitless desire to subvert and corrupt and destroy.
I think the art of the Phrexian's captures quite well the horror that man would wrought on itself if given the technical ability.
