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.
That would solve the Fermi paradox too. Smart species stayed on their home planet, dumb ones tried to leave it. While trying, they ruined their best chance of survival. While in space, they found out that survival out there is nearly impossible without a planet. That’s why we don’t hear from them.
