I would hope that by the time something like this launched to the general public, it would be a service rather than an expected purchase. Like self-driving-flying taxis.
It doesn’t make sense to have everyone owning their own when they will probably be largely autonomous to avoid issues with individuals driving them (not that everyone owning a car makes sense either, but I digress), so the maintenance shouldn’t be an issue either.
I’ve been doing these for years… they don’t work as intended for more than a year or two, and then become pretty unstable. Even the lady who created it went back to low-maintenance (as opposed to zero input) systems after a few years. Still with the dirt and all but not without water movement and stuff.
