Sorry, I meant "destroy the planet" as in lifeless/only single celled organisms.
And you can kind of see humanity as "just another big asteroid impact". Nature will recover competeley over the next million years or so. That's what I meant with mass extinctions being kind of inconsequential for the planet as a whole on geological time scales.
Obviously mass extinctions are also bad besides their effect on human society, I just meant that that is mostly a spiritual one thats hard to measure, about lost potential and eradicating a species. As a thought experiment, is eradicating a disease, a form of life, inherently negative? Mosquitoes? Do you agree that it's a big achievement that we eradicated small pox? What if we eradicate all existing diseases?
