From a live tweet of the proceedings around the lawyer caught using ChatGPT:

"I thought ChatGPT was a search engine".

It is NOT a search engine. Nor, by the way are the version of it included in Bing or Google's Bard.

Language model-driven chatbots are not suitable for information access.

Honestly, this lawyer is actually lucky, bc he is working within a system that was able to catch his misstep.

When MSFT, GOOG & others present their chatbots as a replacement for search, they are setting people up for similar fails, typically in much less regulated spaces.

@emilymbender Other take. ChatGPT is /not/ Bing, Google, etc. And the lawyer wasn't using them. Those are marketed as search aids, and if they make up search results I think there's an argument to be made about not being fit for purpose. They've had to go to a lot of engineering to try and constrain LLMs to actual search results.

ChatGPT was explicitly not that. That lawyer is lucky he wasn't disabarred for incompetence.

@bradedwards @emilymbender I think @bradedwards makes a good point. ChatGPT doesn't pretend to be, or present as, a search engine. Even if it could be construed as such, surely a lawyers duties extend to double-checking case citations...
That said, many of the cautions and calls for greater regulation resonate
