Like, we’re destroying the one place we know is a sure bet on where we can prosper if we keep it healthy, but instead the world’s richest man is trying to expand to other planets while this one’s ability to sustain life is in jeopardy. IMO that makes us potentially a very stupid species compared to a species that doesn’t really care about meeting other aliens because they value the life on their own planet far more than we do.
If all it takes for a species to never leave their planet, is just a few bad eggs, then that would be a defining great filter. All life eventually develops idea of altruism (helping others without anything in return) but that makes egoism even more beneficial strategy, because egoistic individual will have much more resources and higher chance of survival than altruistic one.
