Why is that "sad"? Nature has gone the same path. We have basic defenses that are "on" all the time (passive immune system - nonspecific), and we have an adaptive response that reacts to what actually happens to us, which also means threats we actually encounter will be recognized and fought more quickly and better in the future. Or houses - having lived in the US, those front doors are at least an order of magnitude…
It may be sad for security researchers.
Or for end-users who got their data breached, and aren't compensated fairly.
