Literally everyone would get this. It would make the world so much healthier--enable everyone to easily diet, let people subscribe to healthy meal plans, etc.

It would pay for itself even at astronomical prices, via health benefits, no need to go out for dinner, and reduced food prices via making things from scratch.

Buying in bulk would be more common and much easier. So much comes from grain, sugar, salt and yeast. Much less food would be wasted--no need to batch cook anything and ignore the leftovers. The robot would be baking your bread, making donuts and croissants, tortillas, tortilla chips, mayonnaise, yogurt, sauerkraut, pickles. Things we never consider making on our own, that are generally considered the base components to make other things. I think it could easily offset $300-$1k in monthly expenses for just about everyone.

My assumptions are that it can be tailored to follow a recipe, of which many widely-published recipes are created/curated by chefs and experts, and once that is done the robot rarely, if ever, fails to produce the very best version of the dish.

If the only hindrance is just sitting down and writing the code, someone ought to get busy, because this is about as impactful of a development for the planet as any could be.
