People got extremely angry over a single blog post having a first draft written by an LLM, despite it being rewritten entirely before publishing. There is at least one accepted RFC that started the same way. As best as I know, that was not public knowledge until now.
I'm deliberately not disclosing which RFC was initially drafted by an LLM, as it's not relevant. Just know that it's far more pervasive than you realize. It's no reason to attack someone, personally or professionally.
