The primary danger of a tool like ChatGPT is that it will be used to build fake consensus around a topic, or perpetuate disinformation, via AI-controlled bot accounts or massive content farms. None of the measures OpenAI has put into place will combat this. If I wanted ChatGPT to tell me why Ukraine should surrender to Russia, I could make it do that. That's a perfectly legitimate and reasonable political stance—albeit also one which Russia might be interested in perpetuating.
The danger is not in the type of content ChatGPT can generate, but the sheer quantity of what it could create—and the fact that it really is indistinguishable from a human.
