I believe in true infinity where there's is limitless planet and universe but nothing like cheesy parallel universe but so many possibilities of different planets makeup environments and possibly for evolution differents planet to planet.
For instance mabey other planets species meda is 6 lims because of low gravity flight is easily achieved honestly it's kinda a medical that we can even leave earths atmosphere with how much gravitational force pulls use back to the planet.
End game is a lot more advanced then right now were still in incidence as a civilization.
End game is not only exploring space but a universe level society were we can provent catastrophic catastrophes that we thought impossible.
Most of what we achieved so far was unconsevible to people even 1000 years ago. Never mind 5000 years ago.
I think technology like cyber punk teck will still be old school compared to bio technology that we can combine together robots can't and simply won't over take use because it be self destruction anyway.
I believe Humanity will die out naturally but not for the reasons we think I think we will evolve to no longer fit the human limitations.
