I want one, not that I'd have any real use for it. I have about 5 square meters of garden, a mallet, and some poles. I could deal to those weeds myself.
I think one negative thing it does, though, is remove another avenue of unskilled labor. Some people just can't upskill - and some can, but don't have an avenue for employment afterward, no matter how hard they work. Some places just have no demand for other skillsets.
