that's actually a fascinating idea. think about how humanity solves the environment problems and fusion works out, bringing global peace and prosperity for once. Now a smallish rock comes from space. We don't see it, because of "we go to mars, bro"-elon making ground based astronomoy infeasible and debris from crashes from his great internet satellites making 9/10 new launches fail. so, even if we saw it, we couldn't launch a nuke to deflect it. BOOM. There was the USA and Elons android son is just reduced to dust by his daddies hybris.
