I feel like that's the killer app for fridges, if only appliance makers weren't stuck in the stone age.

Camera in a fridge? Solves a problem no one has ever had (since the invention of doors).

Actual sensor fusion between shelf weight scales + image recognition + a "light touch" UX model to predict current stock? And reorder?

Could close the loop and automate the entire "essentials" grocery experience. And actually free up useful time for people.
