Sometimes, “somewhere else” is upward on the value chain and is thus an improvement. Former plowshare-pullers become horse-steerers become tractor drivers. Each new invention does have it’s attendant complications, but they tend to be nicer than the basic, first job. Ie, I’d rather be a tractor mechanic than a plowshare puller. I’m glossing over generations of social upheaval and re-skilling here, but that’s the pattern so far.
