I think a lot will depend on whether nuclear wars break out but yeah, even in the worst case scenarios I don’t see civilization dissappearing entirely. And honestly it all kinda makes sense to me. Nature has to regulate itself somehow. If one species becomes too dominant things get tipped out of balance. If you have an infection because an organism that is usually present in small numbers on your body has turned predatory and is growing beyond sustainable levels you develop a fever until things are back to normal. It’s the alternative to dying. (Matrix Elrond had it right)
