I had a software dev job at a small agro company about 10 years ago, where I learned that modern harvesters weigh what they harvest and record the location before sweeping it into a hopper. From this data they produce a yield map that helps them decide how to adjust how they program their machines next year, in terms of seed spacing, watering, and applying various products to maximize the yield in each spot. I mentioned lasering bugs as a joke and they said that was either real or coming soon.
