Probably not the secretary, accountant or dispatcher whom they replace. And for every programmer created to develop for these devices, there will be 10, 100, even 1,000 desk jobs which will vanish.
The best and brightest will find jobs as these programmers; the rest will be left to fend for themselves - to find another meaningless job with a tiny wage, so they can live.
This, as something of a tangent, is why I support basic income.
