I wonder if this is this just the law of diminishing returns at play?

My thinking being, it's been a few months since I thought the code generation machine was the problem, rather than my interactions with the machine. A month is a long time in AI.

What I mean is, these things are about as smart as they need to be already for the average SWE. I don't think this is true for those solving the really big questions like curing cancer.
