A building spanning 2,315 acres is almost 4 square miles in size. It dwarfs any building on earth and is intended to provide end-to-end chip manufacturing starting with design, fab, quality control, and packaging. And arch-Technocrat Musk says he needs all this to build his own cars, robots, data centers, and spaceships. Don't forget that Musk's grandfather was the head of the Technocracy movement in Canada during the 30s and 40s.
