Many programmers don't write long text; their way of getting a deep understanding of a problem domain is to build something, is to write code - in a process very similar to writing a long piece of text - it has the same reflection and externalization of thought.

The widespread introduction of LLM code generation is very destructive to that.

Perhaps LLMs can be brought to support human cognition in the same way writing can; but that has yet to be designed and it does not seem to be the way things are heading.
