I've done that, too. It's a bit like a dream where it's not clear what's real and what's not.
Because it seems natural to me; that's how I've always written... Except, I'm also the bot. Just turn off part of my brain and an endless stream of verbiage emerges, vaguely centered around a theme... Then the real work begins: editing for relevance and imposing a coherent structure.
So, I don't really fault anyone who adopts these new tools for the task. But I have some strong feelings about the lazy editing.
