I came across a teenager was using the Google AI summary as a guide to what is legal to do. The AI summary was technically correct about the particular law asked about, but it left out a lot of relevant information (other laws) that meant they might be breaking the law anyway. A human relevant knowledge would mention these.

I have come across the same lack of commonsense from ChatGPT in other contexts. It can be very literal with things such as branded terms vs their common more generic meaning (e.g. with IGCSE and International GCSE - UK exams) which again a knowledgeable human would understand.
