Not at all. But I think one's feelings on global warming & nukes can be influenced by previous exposure to eschatology. I was raised in American evangelicalism which puts a heavy emphasis on the end of the world stuff. I left the church behind long ago. But the heavy diet of Revelations, etc. has left me with a nihilism I can't shake. That whatever humanity does is doomed to fail.

Of course, that isn't necessarily true. I know there's always a chance we somehow muddle through. Even a chance that we one day fix things. But, emotionally, I can't shake that feeling of inevitable apocalypse.

Weirdly enough, I feel completely neutral on AI. No doomerism on that subject. Maybe that comes from being old enough to not worry how it's going to shake out.
