SpaceX Will push to new technology to improve the most important part of TERAFAB. These are the secrets that will enable 50 times more chips by 2030-2035 and the thousands more by 2040-2045. They only replace and improve the light source, which is about half of the cost the $400-800 million EUV systems. The light source power limits the speed of wafer production. Elon and Terafab need 10 times to hundreds of times more chips.
