@lcamtuf I agree completely. I've of course experimented with the idea myself - asking an LLM for a blog post on a particular topic - and the results were okay, but it wasn't my "voice". I even went back and said "read these blog posts I wrote previous to get a flavor of my style" and it was better but still lacking. And repeating this long term you end up eating your own tail.
At best I think it can come up with good outlines that I may or may not end up using, but decent blogs? Not really.
