World models, humanoids and simulation limits

This week we sit down with three founders building at the frontier of AI in space, autonomous hardware, and software reliability: Philip Johnston (StarCloud), Boris Sofman (Bedrock Robotics), and Spiros Xanthos (Resolve AI). We dig into why data centers are heading to orbit, how AI is taking the wheel on construction sites, and whether the industry is moving too fast for its own good.

We explore how physical infrastructure, real-world autonomy, and AI trust are reshaping the industry from the ground up.

• Sam Altman vs. Space Data Centers: He said it won't matter "this decade." But Philip breaks down why the economics of space compute are about to flip.
• The Construction Labor Crisis: Half the skilled workforce is retiring in the next seven years while data center construction spend hits $700B this year alone. Boris explains why autonomous excavators aren't replacing workers, they're the only way to keep up.
• AI Broke Amazon's Code: Generative AI is shipping software faster than engineers can understand it. Spiros warns that accelerating code velocity without upgrading reliability is a disaster waiting to happen.
• Automation Bias & Skill Degradation: What aviation taught us about over-trusting autopilot, and what developers need to learn fast.
• Why Americans Don't Trust AI: A KPMG survey puts AI's favorability between ICE and Iran. The panel debates whether healthcare, education, and construction are the three wins that could turn the tide.
• Karpathy's AI Research Agent: A weekend project that fires off entire teams of AI grad students running experiments overnight. Is this what automating the scientific method actually looks like?
• Anthropic vs. the Pentagon: The U.S. government threatened to label a leading domestic AI company a supply chain risk. Who gets to decide how AI is used in warfare?
