The only way you can even come close to automating farming is through massive conventional monoculture systems. These systems destroy the soil and sacrifice genetic diversity to achieve this goal while producing a glut of a single crop that ultimately drives the value of that crop into the ground.

Humans are incredibly efficient - our pattern recognition ability on a per watt basis is way beyond what we can do with machines. Not to mention we handle environmental irregularities far better than most robots, and we have far more task flexibility. We have millions of years of evolution behind us to make us efficient foragers, it is silly to think we're going to beat that with a few hundred years of science behind us. Instead, we need to figure out how we can make agriculture an enjoyable career instead of soul crushing toil.
