Before this comment is being downvoted, please note the irony. The AI models may solve some technical problems, but the actual problems to be solved are of a societal nature, and won't be solved in our lifetimes.
For mankind, the really big problems aren't going away any time soon.
But -- and it's a big but -- many of us aren't working on those problems. I'm ready to agree most of what I've done for decades in my engineering job(s) is largely inconsequential. I don't delude myself into thinking I'm changing the world. I know I'm not!
What I'm doing is working on something interesting (not always) while earning a nice paycheck and supporting my family and my hobbies. If this goes away, I'll struggle. Should the world care? Likely not. But I care. And I'm unlikely to start working on solving societal problems as a job, it's too much of a burden to bear.
