Well, there's a difference between inevitable doom unless something changes, and inevitable doom that could only have been prevented if something changed fifty years ago. Like your average Blade Runner or Cyberpunk 2077 or other setting will eventually destroy the planet and kill everyone, sure, but there's still a human agency there that could at some point replace a system leading to that with a system that doesn't. In Androids, the time to not make a fatal error was before World War Terminus.
