“Poor people in Africa and elsewhere have far more acreage and still starve.”
Part of it is the labor required, part could be the learning curve.
Robots will transform both. They will start work fully loaded with best practices, and wirelessly get updates when available. In a home garden, they could hunt all night, killing every invasive bug, one at a time, or just blow them away every day with the water spray. Perfectly consistent weeding and watering.
Indoor farming (underground, underwater or multistory) is becoming more feasible over time as well, as LEDs grow cheaper to buy and operate, and are tuned to the optimum frequencies of light for the crop.
I look forward to robot’s farming.
