This has been the dream driving smart refrigerators for literally decades: if you know what food they have, you could sell them ingredient li so they could take their existing theta and digeut and make dish sha. Advertisers have wanted this for a long time. But no one has found a use case that is actually compelling to customers to get them to buy such a refrigerator. This is actually similar to the Alexa: Amazon invested in the project expecting there to be a lot of purchases through it, but mostly it gets used as a timer or to play music and not much purchase volume goes through it.

Maybe people will accept ubiquitous digital surveillance enough that they accept someone else knowing what they have in their pantry and refrigerator, but so far it isn't a thing.

Who follows recipes to produce every meal that they eat, anyway? I just look in the fridge, select some vegetables and a protein, and bang that together into something edible using spices or condiments most nights. But I'm not going to outsource that to my fridge because I'm a lot faster at thinking through all of that then my fridge would be. I do it entirely without thinking.
