Indeed. Sure, lawns do have their place, like for playing sports or for kids to play around. But otherwise, what a waste. Just plant some local flowers or whatever and have a meadow.
As an example, at some point my father stopped bothering to mow his lawn all the time (basically only once per year). It's now a nice meadow with all kinds of grasses. Frogs, butterflies, dragonflies, bees like it.
An additional issue with robotic mowers is that they tend to kill hedgehogs.
That's only an option in areas where the township will allow it.
Big reason to cut the grass is to keep pests away from the house.
That said, I rather consciously arrange deadfall along one steep bank between our house and that of a neighbor so as to encourage/foster lightning bug egg laying/larvae/pupae.
