I think that's somewhat reasonable, but not always: the effort of researching and of writing yourself will teach you better then reading something someone else wrote, especially an LLM that will get things wrong in surprising ways that a human would not.

I'm not saying you should never do this: our time is valuable, and we shouldn't spend it on things that are not genuinely worthwhile to us if we can help it. But we're still losing something by having an LLM write for us, even if the intended audience is just ourselves.
