The most likely source of lock-in would be the tractor and farming equipment vendors. Precision farming requires up-close imaging and other sensing at each plant, tree or small patch of grain. Precision watering, fertilizer, pesticide and herbicide (for weeds) application reduces costs and increases yields. High resolution imaging with machine learning can detect disease before it spreads. The whole setup also lends itself to refined yield predictions.
All round fantastic stuff, but it depends on the farm equipment platform to routinely take it all past every plant, and there-in lies the lock-in potential, that probably explains a lot of John-Deer behaviour.
It’s a patent issue.
