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.
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.
I think the key point why this "reverse cyborg" idea is not as dystopian as, say, being a worker drone in a large warehouse where the AI does not let you go to the toilet is that the AI is under your own control, so you decide on the high level goal "sort the stuff away", the AI does the intermediate planning and you do the execution.
We already have systems like that, every time you use you tell your navi where you want to go, it plans the route and gives you primitive commands like "on the next intersection, turn right", so why not have those for cooking, doing the laundry, etc.?
Heck, even a paper calendar is already kinda this, as in separating the planning phase from the execution phase.
For "stuff" I think a bigger draw is having it so it can let me know "hey you already have 3 of those spices at locations x, y, and z, so don't get another" or "hey you won't be able to fit that in your freezer"
