My two cents is that the parts of the job that are more like product management will become more dominant but still not exclusive, and the parts that were more like coding will become less dominant but still not vanish. Many of us, as you describe, already do jobs that look a lot like this. But for me, it's not consistently that way; there are periods where I'm almost entirely coding, and periods where I'm almost entirely doing communication. I do expect a shift in this balance over time.

The other thing that I spend a huge amount of my time doing - consistently more than writing code - is debugging. Maybe these models really will get to the point where I can train one on our entire system (in a way that doesn't hand over all our proprietary code to another company...), describe a bug we're seeing, and have it find the culprit with very high precision, but this seems very far from where the current models are. Every time I try to get them to help me debug, it ends in frustration. They can find and fix the kinds of bugs that I don't need help debugging, but not the ones that are hard.
