Nah, he's just talking to an LLM.
“I’ll go down this thread with [Chat]GPT or Grok and I’ll start to get to the edge of what’s known in quantum physics and then I’m doing the equivalent of vibe coding, except it’s vibe physics,” Kalanick explained. “And we’re approaching what’s known. And I’m trying to poke and see if there’s breakthroughs to be had. And I’ve gotten pretty damn close to some interesting breakthroughs just doing that.”
And I don't think you can brute force physics in general, having to experimentally confirm or disprove every random-ass intermediary hypothesis the brute force generator comes up with seems like quite the bottle neck.
We live in a world where the US vice president admits to reading siskind AI fan fiction, so that ship has probably sailed.
