That makes sense - it is an LLM, not a reference library.
Part of using a tool well is understanding what it is good for and what it is not. If you are .looking for citable references... or even full factual accuracy, it is the wrong tool.
It's the wrong tool at the moment. But full factual accuracy and citable references is something the users will likely demand from these chatbots as a minimum requirement. I'd be surprised if it won't be attempted incorporated at some point, not too distant.
