Wouldn’t the best or worst outcomes of AI be many years away?

There simply aren’t enough robots to do something like this on global scale and it would take a long time to get there. Plus it would take a lot of human intervention to get to a point where the robots are able to build more robots. The apocalyptic scenarios I hear are painted with drones flying over your city, robots roaming the streets.

I get the models are improving and the concept of RSI but there are physics limitations to getting materials out of the earth, refining it, shipping, manufacturing it, assembling it, and ope
