LLMs have felt to me like they excel in one particular skill (being able to make connections across vast amounts of knowledge) and are basically average, otherwise. If I'm below average at something (painting, say) the results astound me. But if I'm above average (programming, writing (I like to think)), I'm generally underwhelmed by the results.

I used Claude a lot for planning my current fun project. Good rubber duck. It liked all the suggestions I pitched for the design, but I only went with the last one after discarding the others.

The others were all fine and would have worked, but they weren't the best that I found.

Back to the point, if we're getting average guidance from the AI and we're just offloading our thinking process at that level, then I could sure see it panning out like TFA says.
