Depends where you live. In the midwest you might legitimately need to mow 3x a week and you might have a huge lot. If you say screw it and let it go to knee high weeds, city might show up and cut your grass and fine you for it.
Most lawns in North America are Kentucky Blue or ryegrass which are what produce the eyesore.
But lawns in general are a pestilence.
But as far as when I owned my own home, cutting the grass was just part of my routine and at least guaranteed some physical activity instead of working all day during covid.
It's also worth noting that owners have changed their behavior to favor their robot vacuums, though I have not read any similar examples for robot lawnmowers yet.
I just pay someone $50/week to mow my lawn and I pay zero attention to it. If we have a mini-drought and the grass turns brown, oh well.
