Elon Musk's US$20~25 billion “TeraFab” chip project

Elon Musk on Saturday announced what he calls the "Terafab," a semiconductor manufacturing plant to be located in Austin, Texas, that will produce chips for Tesla vehicles, SpaceX spaceships and Optimus humanoid robots. Currently, Musk's companies rely on other semiconductor manufacturers, including Samsung, to provide chips.

In a half-hour presentation on Saturday, Musk outlined his rationale for the Terafab factory, and it goes far beyond electric cars and robots. The new plant will manufacture the type of potent chips that Musk says are needed to transform humankind into "a galactic civilization," evoking the fictional worlds depicted by authors such as Isaac Asimov and Iain Banks.
