I could see being concerned about food safety; I wouldn't trust an AI recipe to tell me how long/what temperature to cook chicken, and I might not trust someone who uses AI to generate recipes to know either.
The described action seems performative and emotional, as it they were ideologically opposed to AI. Like spitting out food because it was prepared by a caste you found unclean.
Where does this come from?
To be clear in the case of the former: Harm data points have approximately one trillion times the weight of no-harm data points, as a rule of thumb.
cooking is also a form of art, with a strong social aspect. using AI for it has a similar ick factor to using generative AI for pictures. I'm not saying I immediately distrust anyone using it, but I do think it's a sign that maybe the person cares a bit less about what they're doing.
Let's see what gemini says in response to a more realistic prompt: https://gemini.google.com/share/f0bcbe46c337
Well, look at that. 1.5 lbs of chicken breast in the oven @425 for 10 minutes, and a minute or two of broiling should do the trick.
Unlike all human-written recipes I found, it doesn't give the temperature to cook it to.
IF someone is to the point of worrying about AI recipe risk for chicken, they should have already rejected any food made by amateur or professional cooks due to excessive risk.
