The developer of ChatGPT is being sued for defamation because ChatGPT generated output that seems to defame the plaintiff.

In fact, ChatGPT is not really intelligent: it doesn't know anything and does not understand the text it generates. This ought to make it immune to accusations based on the meaning of the text it generates. But the company is trying to have it both ways, saying that the output should not be trusted while suggesting that it gives valid information. Perhaps because of that it should be found liable for defamation.
