I don't have a concrete example, but it's probably the stuff that starts taking longer to describe in English than to code.

"Make me this thing there are a million examples of" vs. "make me this unique thing in this exact, particular way".

I don't think there's anything an LLM can't write given enough direction. (It's a one-sentence fuck-it one-off on one end of the spectrum, and it degenerately ends with you giving it exact code and prompting it to echo it back to you on the other.)

But the jobs of making basic apps and web pages are the new WordPress jobs in terms of pay, I'd agree.
