I like being able to see the thing I'm going to get and holding it in my hand.
The grocery industry relentlessly optimizes for implicit choices over expressed preferences. Nobody is asking for misters, colored lighting, skeumorphic veggie bins, and wide open sightlines in the produce aisle. Stores do it because customers buy more when they do. The same thing will happen to in-store shopping if consumer preferences swing ever swing that way instead.
I like not going to the store more.
Because tips are important to the income of delivery shoppers, I find that I generally get good produce selections. It might be difficult to transition that particular incentive to robots, but the point is that delivery items don't have to suck.
The only thing I really still pick out by hand every time are beef briskets. Pork shoulders tend to be uniform enough that randomly picking a cryovac works out, but there's a good bit of variation in brisket that makes a difference with the final product, at least when the brisket is prepared with a smoker. YMMV
