Metal Collar

The three collars

Masayoshi Son introduced the term around 2017 and restated it with more urgency in a later interview: "We're going to have white collar jobs and we have blue collar jobs, but there's a new collar that's going to start, it's called the metal collar. And the metal collar will not only replace most blue collar jobs but many white collar jobs too."¹ His point is that AI is not simply automating physical assembly work, which has been happening since the 1970s. The newer, second-order shock is cognitive work, the management, legal, and financial roles that were assumed to be safe from automation, and metal collar is his unified name for the layer that spans both physical and cognitive automation at once.

Time liberation, not mass unemployment

Son's framing of the outcome is explicitly optimistic, distinguishing his position from more dystopian labor-displacement narratives. "We don't have to work eight hours a day. We don't have to work ten hours a day. Maybe three hours a day or four hours a day. And most people can still have enjoyable and productive working days." He draws the analogy to the shift away from subsistence labor: a century earlier, people had to work simply to secure water and food each day, and now that labor has been automated away without eliminating human activity itself, only redirecting it toward higher-order work. His claim is that the metal collar completes the same transition, with routine physical labor such as cleaning streets or manufacturing goods eventually handled by robots, freeing human hours for what he calls more human-like activities.

A more cautious counterpart

Son's optimism about the outcome contrasts with a more pessimistic framing associated with Alex Karp and Dario Amodei, who describe roughly half of early-career white-collar jobs as being at risk and treat political backlash, up to and including calls for nationalization, as a near-certain feature of the transition rather than a remote risk. The two positions are not strictly incompatible: Son is describing a steady state once the transition is complete, while the more cautious framing is concerned with the transition itself, and Son's account does not appear to budget for the political consequences that the more cautious framing treats as almost certain.

Connection to a wider agentic shift

Son's coinage predates the broader vocabulary around an agentic economy by several years, but it describes the same underlying phenomenon from the labor side: AI agents do not merely assist with a task, they take it over outright. On this reading, a three or four hour working day is the equilibrium in which humans direct AI systems rather than personally executing the underlying work, which raises the same question from the other direction, what work itself comes to mean once cognitive execution is something a system does on a person's behalf.
