I'm a bit puzzled that these climate scientists give our civilization to the end of the century. I can't see it lasting until the middle of the century, in the context of the climate and ecological crisis. This is not inevitable, it can be avoided, but it is this total denial of the climate and ecological crisis, what it means for our societies, and this bizarre false belief that we can carry on with business as usual, that is making early collapse inevitable. There is no scientific basis for this AI threat stuff, it is pie in the sky imagination. Sure AI is a real threat, in terms of the building of all these energy guzzling, water guzzling data centres. Plus it is predicated on replacing most of the human workforce, where most people will be seen as surplus to requirements. But it is totally bizarre that they ignore the real threat from the climate and ecological emergency, backed up by massive scientific evidence, and dwell on the fevered imaginings of some computer nerds.
