As others say, not necessarily. The breakeven point for jobs like Amazon may be quite low (or high? I mean simply "not yet there").

I'd say that we'll know it works when robots with those hands start turning out on the Russo-Ukrainian frontline en masse, because it is there where the lack of manpower has the most pressing and brutal consequences, and cannot be mitigated by usual peacetime incentives (e.g. better benefits).

That frontline has already sucked in all the automatization innovations of the last decade, as long as they proved themselves in combat.
