I agree that ChatGPT's ability to generate convincing arguments for complete BS is concerning. But I'm not convinced it's a clear negative, in the long run. Humans have been concocting convincing arguments for complete BS for millennia. Perhaps having non-humans generate such arguments will make humans less inclined to believe BS based on such arguments. Eventually AI's will be able to think logically, barring any catastrophes that prevent further improvements. And eventually, the AI alignment problem will either be solved or human civilization will fail in one way or another. In the meantime, things will be very strange, but not clearly better or worse.
