Amen to this. As soon as you ask an LLM to explain something in detail that you’re a domain expert in, that’s when you notice the flaws.
For example, I’m not a domain expert, but I was looking for an RC motor for a toy project and OpenAI had happily tried to source a few, with Deep Research. Only the best candidate it had picked contained an obvious typo in the motor spec (68 grams instead of 680 grams), which is just impossible for a motor of specified dimensions.
It's funny you say that because I was going to echo your parents sentiment and point out it's exactly the same with any news article you read.
The majority if content these LLMs are consuming is not from domain experts.
This isn’t just “shit in, shit out”. Hallucination is real and still problematic.
