> I wonder how much of this is simply needing to adapt one's workflows to models as they evolve and how much of this is actual degradation of the model,

I also wonder how much people are willing to adapt to non-reliability for the sake of laziness instead of, at some point, do a proper take the lead and solve a problem if you have the knowledge + realiable resoources.

It seems to me, the way you phrase it, that anything a human comes up with when coding must go through an LLM. There are times it helps, there are tasks it performs, but I also found quite often tasks for which if I had done it myself in the first place I would have skipped a lot of confusion, back and forth, time wasting and would have had a better coded, simpler solution.
