In biology, all species eventually branch out into new species.
It’s just the nature of the game.
So, who would deny that humans are on a precipice, about to branch off into breakaway civilization(s)?
The thing about space is that it transforms biology, so you might want to make yourself comfortable with the concept that your great grandchildren will become gray aliens, with expanded brains but weakened bodies due to the lack of gravity.
We are blasting off space ships, yet no one has hacked the way to produce artificial gravity in a vacuum.
