“Expect golf course mowing positions to vanish within a few years. Many yard work service positions will vanish as well. Zero-degree mowers are in widespread use. It will not take much to equip them with self-mowing capability. So instead of a homeowner farming out mowing (or mowing himself), envision a system where the homeowner maps the perimeters of the lawn and the perimeters of any flower beds that need to be avoided, and the mower does the rest. Rather than pay someone to mow the lawn twice a week, a fully autonomous mower would pay for itself in a year or two most likely. And the higher the minimum wage, the faster the payback of purchasing such equipment.”
