I've also tried — out of curiosity rather than necessity — putting legal questions to ChatGPT, and not only did literally every single case law citation I had the means to check not really exist, the statue laws it quoted me didn't apply in my case.

I might have been particularly unlucky, but on the other hand, my understanding of the law is that passing the bar exam (the standard that ChatGPT reached) is for humans just the metaphorical foot in the door to allow on the job training.

Of course, if you are a lawyer and you have the skill and means to check the output, then it will likely still help you for the same reason someone fresh out of law school would still help you, and for the same reason that I would describe ChatGPT's code as "intern to fresh graduate" and yet still use it.
