All this AI doomerism is hiding the obvious and immediate harm that will cause a mass extinction event. Funnily enough people at Anthropic are predicting the end of the Anthropocene, completely absolving themselves from any responsibility for the actual reality that the Anthropocene is defined by human made geologically noticeable changes. Like causing a global climate catastrophe.
Mass extinction event already happened though. Most known species became extinct because of humans.
The existential risk people are worried about a much shorter timeline - like the next 5-10 years. Climate change is serious but very unlikely to lead to anything like ending the Anthropocene in the next 5 years.
It's possible to have more than one existential risk at a time. We even have a third, since nuclear war doesn't seem completely impossible these days. We probably shouldn't ignore any of them.
