Andy Warhol called his studio The Factory. Between 1962 and 1968, it produced silkscreens, films, sculptures and 'happenings' at a scale no single person could have made alone. Warhol didn't run the presses but he decided what was worth making, what got signed, and what went on the walls of the rich and famous. The judgment was his but the execution was outsourced. This worked because he had spent years as a commercial illustrator developing the eye that made his taste and judgment worth trusting.
Rubens ran a painting factory in Antwerp in the 1600s. Raphael had a workshop producing work to his direction before he was thirty. Separating inspiration and direction from execution is not a new arrangement. It is how the best creative work has always scaled.
