Automating picking of a many types of vegetables is a hard problem, and the human labor costs are extremely low. I'd be surprised if we develop anything that even approaches the cost efficiency of your average migrant farm worker in the next 30 years. We have millions of years of evolution as efficient foragers behind us.

Additionally, one thing that micro-scale farmers are doing is experimenting with new and different breeds of vegetable. Some are even breeding their own crosses. Some of these are substantially different in taste and texture, and most are visually appealing. You might not care about that, but to people who enjoy cooking, this is great, and worth paying for.

Small scale agriculture has a good future. People seem to be into the whole local thing, vegetables (and vegetarianism) are getting trendy, there is a huge surge of food culture. All good for the small boutique producer, who can offer higher quality and more exotic products.
