Eventually, there would be no more hosts if it keeps this up, or if any survive, they may not be very forgiving. Even for a fungus, not very smart. My advise would be for it to ease up on this extinction business.
Microbes aren’t “intelligent.” They adapt in ways which are intelligent in some ways. Unfortunately, they adapt only by the absolutely lethal varieties ceasing to exist after they’ve killed off their host. And in this case, their host isn’t a single organism, but an entire order of organisms.
