ZERO HUMANS ON THE LINE. ONE ROBOT THAT PICKS UP A PART, INSTALLS IT IN A CAR DOOR AND REPORTS: "DOOR SECURED." This is what a Tesla factory could look like once Optimus hits the assembly line. Why Musk is betting on it: •Tesla employs about 125,000 people; •a US auto worker costs $60+ an hour with benefits; •Optimus is promised at $20,000–30,000 at scale; •$25,000 over 5 years at 16 hours a day comes to under $1 an hour; •Musk wants to build up to 1 million Optimus robots a year; •Tesla shareholders approved a pay package for him in which one of the milestones is 1 million robots delivered. A human needs an 8-hour shift, lunch, weekends and vacation. A robot just needs a charger. For now these are projections. But every part installed without a human is one less hour of labor on the factory floor.
