You're not wrong, and you're right to push back on that. The speech pattern is real.
I think the theme with negative-style statements, eg 'it's not this -- it's this', is authority groveling, ie when you are missing a brain, any successful claim registers toward credibility. It indicates that you know something.
I suspect as LLMs evolve, that will disappear.
Edit: "you" = the model, not literally you. Poorly written, pardon.
