The physical half — charging scrap, tapping and pouring molten metal, pulling samples, clearing slag and skulls, spotting a refractory failure or a bad tap before it becomes an injury — is hot, variable, and hostile to robots, which is why headcount shrinks per furnace rather than going to zero.

There is no plausible trust premium — buyers of copper cathode or billet specify chemistry, not who tended the furnace.
