Maybe I don't understand exactly what you're describing but why would anyone pay for this? When I bring home the shopping I just... chuck stuff in the cupboards. I already know where it all goes. Maybe you can explain more?
When I hire a plumber or a mechanic or an electrician, I'm not just paying for muscle. Most of the value these professionals bring is experience and understanding. If a video-capable AI model is able to assume that experience, then either I can do the job myself or hire some 20 year old kid at roughly minimum wage. If capabilities like this come about, it will be very disruptive, for better and for worse.
If you can't get a tutorial on your exact case you learn about the problem domain and intuit from there. Usually it works out if you're careful, unlike software.
Case in point, I remember about ten years ago our washing machine started making noise from the drum bearing. Found a Youtube tutorial for bearing replacement on the exact same model, but 3 years older. Followed it just fine until it was time to split the drum. Then it turned out that in the newer units like mine, some rent-seeking MBA fuckers had decided more profits could be had if they plastic welded shut the entire drum assembly. Which was then a $300 replacement part for a $400 machine.
An AI doesn't help with this type of shit. It can't know the unknown.
Or you could wear it while you cook and it could give you nutrition information for whatever it is you cooked. Armed with that it could make recommendations about what nutrients you're likely deficient in based on your recent meals and suggest recipes to remedy the gap--recipes based on what it knows is already in the cupboard.
But none of the kitchen stuff we learned had anything to do with ensuring that this week's shopping list ensures that you'll get enough zinc next week, or the kind of prep that uses the other half of yesterday's cauliflower in tomorrow's dinner so that it doesn't go bad.
These aren't hard problems to solve if you've got time to plan, but they are hard to solve if you are currently at the grocery store and can't remember that you've got a half a cauliflower that needs an associated recipe.
Presumably, they won't as this is still a tech demo. One can take this simple demonstration and think about some future use cases that aren't too different. How far away is something that'll do the dishes, cook a meal, or fold the laundry, etc? That's a very different value prop, and one that might attract a few buyers.
