I wonder how much improved robotics will change the picture. Labor intensive practices and crops might become more feasible if we can get robots to do that labor. Afaik agriculture is already moving in that direction with very fancy advanced tractors etc (I don't actually know anything about ag).

One issue that I foresee is that if something needs a very specialized robot, then the market might not be big enough to warrant the development cost. Undoubtedly it makes lot of sense to automate something like wheat or whatnot bulk crop because there is just tons of that around. But asparagus or something might be too niche?
