Grimes County, Texas, is about to become ground zero for Elon Musk's biggest swing yet. It's another crushing loss for California, which, once upon a time, might well have played host to the gargantuan project. Elon Musk is following up the Trump administration's call to ramp up chip production with Terafab, which will sprawl out to one-sixth the size of Manhattan. That's roughly 10 times the size of Tesla's Gigafactory Texas, which itself was launched as another move to evacuate California's rough corporate environment. "We either build the Terafab," said Musk, "or we don't have the chips, and we need the chips, so we build the Terafab."
