> Or should it say it can't be sure and to ask a doctor?

It's an extremely slippery slope to having it say that about even the most basic medical information.

If you don't believe me, try any google search related to something as simple as hangover tips. The AI summary will tell you to call SAMHSA and then brutally stonewall you on anything else even tangential to alcohol.

I can't reproduce your claim. I get a medically correct response from the AI summary and then a link to the Mayo clinic at the top of the search results.
