Climate change won't affect AI, it could just make things shit for a couple hundred years. AI could solve that. Nuclear war might impact AI, but probably only temporarily (assuming we survive) and a war isn't guaranteed. But AI affects: Everything humans read/watch/touch/influence. Forever. Including climate change and our odds of nuclear war. There's no way it doesn't and once it starts there's no way we can stop it forever. Any narrower view is a failure of imagination. The outcome of AI is the outcome of humanity for the rest of our time in the universe.
