The Takeaway: LLMs excel at language tasks but lack the architecture for true intelligence in the physical world; world models based on JEPA are the way forward. Yann LeCun, Meta's former Chief AI Scientist and Turing Award winner, shares why he left to found AI for the real world at his new company. He argues reality is too complex, continuous, and noisy for autoregressive token prediction. World models that predict action consequences and enable planning through search are essential. "LLMs are intrinsically unsafe... they cannot predict the consequences of their actions." He contrasts this with JEPA's non-generative approach that learns abstract representations. LeCun sees five-year world domination for this paradigm in robotics, industrial control, and healthcare.

Box CEO Aaron Levie warns that CEOs are prone to AI psychosis because they're distant from implementation details. They see happy-path prototypes but miss the real work in verification, integration, and reliability needed for sustainable agent value. He advises CEOs to use AI extensively themselves to understand both upside and practical challenges.

Peter Yang highlights Ryan Carson's approach of using AI agents like OpenClaw as chief of staff and Codex/Devin as engineering team. Carson emphasizes understanding every job before hiring, building systems that build MVPs, and treating agents like employees with proper access.

Anthropic's Thariq notes that legacy codebases like Bun will be incredibly valuable for distilling into new forms. He sees a future where every game is cross-platform and legacy software runs on the web. Models aren't quite there yet but will get there.

FPV Ventures partner Nikunj Kothari shares how he uses Claude Code with browser_harness or Playwright to sniff network requests and automate tasks. This bypasses difficult DOM navigation and enables programmatic data access. He predicts websites will need to become headless with payment mechanisms for agents.

Builder Zara Zhang discovered Amphetamine, a reliable Mac app that keeps the computer awake even with lid closed, outperforming terminal caffeinate.

Google Product Leader Madhu Guru observes that arms-length AI mandates from CEOs lead to performative demos and stalled progress, allowing hands-on startups to disrupt.

Vercel CEO Guillermo Rauch states simply: Build a great product to build a great brand. He also praises BJJ as the peak athletic pursuit.

Y Combinator CEO Garry Tan emphasizes that high agency and high taste are the unlock in today's environment.
