The astronaut is extremely optimistic
But he is also unrealistic
Humans are greedy & have been since our ancestors walked the planet
eg - Why do you think there are no more woolly mammoths?
The archaeologists say the cavemen killed them to extinction by driving them off cliffs and into pits. And if they weren't busy killing off much of the wildlife, they killed and even ate each other
so this has been going on since the beginning of time.
And today we still have our greedy dictators & billionaires who live like kings while their own citizens starve.
Unlike many species, people often don't share
They aren't content with equality
They want to feel superior to others
They need to have more than the person below them
This contrasts with other species where the lead or strongest member of the troupe kills another animal but shares it with the other members
ie -wolves or lions
But people almost always want more than the other human being
and they weaponize their wealth to suppress or destroy others.
and they cheat and lie to do it.
Unfortunately, you have to live in the cave much of the time just to survive in this bloody world.
Maybe that's why so many people don't come out of the cave, because they think they'll be next...to be annihilated
The astronaut's plan would work, if it wasn't for the Human species
