We may look back at these days - you know, where not all diseases kill you, and in fact were super easily handled, barely an inconvenience!:-P - and wish to have such things as "antibiotics" again, before bacteria all became immune to them.
Or maybe the world will rally together, and start funding research into alternatives quickly enough for it to matter? Just like climate change too...
It's a good thing that people aren't anti-science now, bc that surely would be a problem if we want to reach that bright shiny happy future we keep hoping for. :-|
