It signals that instead of contributing your own thoughts, you’ve outsourced your opinion to an AI. In serious discussions, it can undermine your credibility, especially if the topic requires critical thinking, personal insight, or expertise. People might dismiss it outright with a “So what? That’s just what an AI generated.”
It can also feel like a cop-out, especially in academic, professional, or nuanced debates where showing your reasoning matters. Relying on ChatGPT as a crutch might make you seem disengaged or unwilling to do the work of forming your own view.
In short: pasting “Here’s what ChatGPT says…” can make your comment look generic, weak, and uninspired—and in some circles, it’s almost a conversation killer.
