Anyone who has tried to use LLM’s knows it’s the exact opposite – that they are a decently useful automation tool for structuring / transforming information as long as you do not venture outside the realms of well-documented and widely established human knowledge. They are useless otherwise
![Travis Kalanick, the founder of Uber who no longer works at the company, appeared on All-In to talk with hosts Jason Calacanis and Chamath Palihapitiya about the future of technology. When the topic turned to AI, Kalanick discussed how he uses xAI’s Grok, which went haywire last week, praising Adolf Hitler and advocating for a second Holocaust against Jews.
“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.”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:qlnirjwff4ibiw3wchmleszo/bafkreiac2szurc5dnw6klquhpjmo7iafg4n6fwmrqyred7jrrph6h6mptq@jpeg)
