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.
Warp drive is still possible with our current understanding, Fusion is right around the corner (at least if we look at the entire human existence) and while most mega structures are fictional, a Dyson swarm is fairly easy to do and completely possible.
Humanity could still go very far till physics and chemistry are the real limiters, but human greed will wipe us out first.
Thanks for the laugh!
