AUSTIN, Texas — Elon Musk used last week's Baron Investment Conference to return to a familiar theme with fresh conviction: the humanoid robot Optimus, he argued, is the product that will eventually dwarf everything else Tesla makes.
The framing is not new, but the emphasis is sharpening as Optimus moves from laboratory demonstrations toward real production lines. Musk has described the robot as potentially Tesla's most valuable product line over the long run, a claim that rests on a simple premise: the market for general-purpose physical labor is far larger than the market for cars.
From pilot lines to volume
The nearer-term story is manufacturing. Tesla is working to scale Optimus from hand-built prototypes to early pilot production, the same painstaking climb the company has walked with every vehicle it has launched. Musk has long argued that designing the machine that builds the machine is the hard part, and Optimus is now in exactly that phase — proving out a production process before volume can follow.
That ramp matters because economics only work at scale. Tesla has already begun sketching how customers might access the robots, including a model built around renting Optimus rather than buying it outright, an approach that could put the technology to work sooner while production climbs.
