Tesla CEO Elon Musk is eyeing San Francisco for his next robotaxi city — to which I say, good luck to you, sir. Musk acknowledged that the company is still waiting on “regulatory approval,” which hints at the uphill company Tesla will face in pushing this process forward. (Get it? Uphill? San Francisco?)

Musk's confirmation followed a late-night livestream announcing xAI's Grok 4, where he claimed the new AI model was smarter than "almost all graduate students, in all disciplines, simultaneously," and could "discover new physics."
