Some techbro needs to start a subscription service for flour pods delivered by drone. Insert them into your $800 flour bank, and then whenever you need flour, you can just use the app to indicate how much the machine should dispense!
edit: the app also provides AI-generated recipes, and every time you use flour you'll automatically earn some FlourCoin cryptocurrency.
Make sure the containers have DRM so the machine can validate that they are genuine high quality Flourz™ Refill Paks before dispensing the flour. Wouldn't want you to just, like, refill them with inferior flour from Walmart or anything.
