It seems much more likely that this was just referring to the ongoing situation with LLMs being able to create exceptionally compelling responses to questions that are completely and entirely hallucinated. It's already gotten to the point that I simply no longer use LLMs to learn about topics I am not already extremely familiar with, simply because hallucinations end up being such a huge time waster. Persuasion without accuracy is probably more dangerous to their business model than the world, because people learn extremely quickly not to use the models for anything you care about being right on.
