That's irrelevant to my point. Feel free to replace "selling" with "distributing" - my point stands: using an LLM to estimate carbs from a picture is a real use case that real software developers are suggesting to real people is a real solution. It's not some contrived idea that the researcher concocted to make AI look bad.

The GP, and much of the thread, is basically acting as if it should be obvious to anyone who is not an idiot that this is not possible to do precisely; and that the researcher just made up some use case that LLMs can't do and wrote a paper about it to disparage AI.
