If specialization were always better then we’d hire a different specialist to press each key on the keyboard. Specialization is only efficient when the specialist can do a better job, and by enough to outweigh overhead. Rough sorting is extremely basic and requires no “training”, so specialization is less efficient, and serves only to shift work to people whose time is valued less.

This is obviously false from the start. the entire problem is that it does require training and people don’t perform the task very effectively as a result.
