That’s rather cruel. Optimizing lawn mowing conserves human and machine fuel/battery, especially on large plots or as professionals or in hot climates. Misapplying optimizations to one’s free time is absolutely in line with your stereotype, but that’s much more a widespread defect of judgment in computer engineers than in mowers.
The same skills used to mow lawns are also used in more complex settings to e.g. tend to farm fields, where you have to account for product wastage versus turning radius versus machinery operating hours. (Thanks, Farming Simulator!)
