> If you were willing to cover your store cupboards with cameras (!), you could track potentially track everything in and out. Maybe scan receipts as well. But this amounts to a lot of information about your home life and domestic economics, and I don't want to just turn that over to a company who'll exploit it. Perhaps what I want is "YNAB, but for food". The problem with these solutions is that they'll never be close to accurate because they don't reflect how people function. We don't keep pristine pantries with nicely organized shelves and perfect containers. We don't purchase the exact same foods consistently and without variation. And there's the unpredictable nature of life. People's pantries are a mess from an inventory perspective and it's not necessarily because people are messy. Food stuffs come in a varying array of packages from the easily tracked (e.g. soup cans) to the difficult to quantify (e.g. potato chips). You would need a dizzying array of image and weight sensors to quantify things and even then you'd run into issues with things like rice, beans, or flour which tend to be put into custom containers. People's eating habits, tastes, and cravings change almost on a daily basis. I might go through 8 jars of salsa in a month or spend 3 weeks two bananas a day and then not touch either of them for over a year. I might start a new diet that changes how I eat and then abandon it a month or two later. Keeping track of and automatically ordering items based on ever changing habits is impossible. The unpredictable nature of life might result in my order of 3lbs of chocolate chips because I'm baking cookies for a school function and then not using them again for half a year or more. My mother might come visit for 2 or 3 months resulting in a routine purchase of certain foods right up until she leaves. I might have to go out of town for a few weeks and so I might stop buying perishables well ahead of my departure. The reality is that no amount of monitoring is going to be 100% perfect and at the same time it adds mental load to the consumer because they need to remember to manage the process lest the end up with 8lbs of bananas the day after their craving ceases.
