I would imagine that the list of digital chores of a very busy businessman are a bit more extensive. Even in your list, groceries is something that becomes digital once you're high enough in income.
The only "selection" complaint I regularly have had is the bananas are nearly always very unripe - like several days from being edible. But then I went to the store myself for several weeks and realized they just never have ripe bananas.
In other words, they're doing as well as I could do if I were shopping it myself.
Then you have a shopping list. You can do the shopping digitally now a days, but once it's delivered, now you have to organize it into the pantry existing stock, probably with a way to ensure older items are used first. This might involve separating out certain ingredients into smaller packaging and freezing some for later use.
That is all very manual, and I don't see how digitizing one part greatly simplifies it, especially if the digitization is error prone.
In a high enough income state, the answer is you hire a personal household chef or something like that. That isn't digitizing the problem- that is outsourcing it.
