Even in the worst case, “all” seems unrealistic, it’s not like humanity didn’t exist before penicillin or electricity.
Realistically we see mass migration, die offs, wars over resources. I don’t think it is likely that the superpowers end up in the Stone Age, even if they do end up very different.
Sure we can make some numbers, human race is mastering of surviving. Still that “all” is focused on normal people like us, behind PCs, that will probably get used too much on counting to services. Probably not back on stone age but competing with the worst apocalyptic movie for sure.
