How Tesla's Giga Press Replaced 1,000 Workers and Builds Cars in Seconds

At the end of 2025, Tesla's Fremont factory ran on more than 1,000 welding and assembly robots. By early 2026, half were gone. Not replaced by newer robots — made unnecessary, because the parts they existed to weld together no longer exist as separate parts. I break down exactly how the Giga Press works down to the 35 milliliters of soybean oil sprayed before every cycle, what a 50,000-ton clamping force actually means, how the Model Y went from 200 structural components to the Cybertruck's 80, and why the next thing Tesla wants to delete is the paint shop.
