True - though only for certain types of labor. Entertainment, sports, software, the arts, but not many others.
You can't scale the labor of being on an assembly line, or the labor of being a lawyer or a doctor or a farmer or an auto mechanic. (You may be able to replace them with software, but that's not the same thing.)
(And, yes, you can "scale" them in a way by giving them better tools. A farmer today with a combine is easily 100x a farmer 150 years ago with a sickle - probably more like 1000x. There's not another factor of 10 available to scale them up right now, though, no matter how hard they try.)
