Counterpoint (more devil's advocate), I'd argue it's better than an LLM writes something (e.g. the solution or thinking through of a problem) than nothing at all.

Counterpoint to my own counterpoint, will anyone actually (want to) read it?

counterpoint to the third degree, to loop it back around, an LLM might and I'd even argue an LLM is better at reading and ingesting long text (I'm thinking architectural documentation etc) than humans are. Speaking for myself, I struggle to read attentively through e.g. a document, I quickly lose interest and scan read or just focus on what I need instead.

Writing is how I think through a problem too, but that also applies to writing and communicating with an AI coding agent. I don't need to write the code per se to do the thinking.
