> restaurant quality meals, for cheap, large selection, with zero effort
If this were ever to happen - and what I know of food chemistry makes me strongly skeptical - you would definitely see it in actual restaurants way before you get it at home. Because for a restaurant, if you can effectively replace a human costing >$40k/yr with a change in supply chain and a fancy machine, you can easily afford to pay $40k for the machine alone. A consumer would never afford that.
(Same goes for fully autonomous cars.)
As for the "reducing food waste" concept - no store actually wants to achieve this. Think about it - actively trying to get people to buy less of what you sell is pretty bad for business.
