> There's little difference between well designed code generated by an LLM and well designed code written by hand

I'd argue that according to the "Programming as Theory Building" viewpoint, there is a potentially significant difference: the presence of a complete mental model of the code in the mind of the human(s) who wrote it.

Whether that actually matters now that LLMs can quickly ingest and "understand" a new codebase and answer questions about it... isn't yet clear to me. I also don't know to what extent prompting with no or minimal coding adequately builds the mental model of how the program works.

But I don't yet find it obvious that the end product - clean, hopefully correct code - is the only value produced and that the craft of coding by hand no longer matters.
