We’ve spent most of our history trying to exterminate each other anyway. This way, we’ll at least have some dispassionate outside referee settling all of humanity’s old scores permanently. No more generational feuds, no more ancient grudges, no more pointless revenge carried out against people who inherited some old guilt from their great-grandparents. We will all just go down the path on which we’ve sent so many species ourselves, and we’ll just be a note in someone else’s xenobiology textbooks, listed under the header “EXTINCT.”
