More likely would be a system that uses cameras to see what you put in, alongside a program to identify what type of item it is, and a record of its estimated time of spoiling. Say you put in a pack of bagels, and the fridge deduces it is a new pack because you haven’t recently taken bagels out. The fridge estimates they will probably last 1-2 weeks. Then depending on how much they are removed and put back in, it might throw a reminder on the screen “bagels still good?” etc
