We're entering a new era of software where a single person, working with AI agents, can build products that previously required entire teams. In this episode of Lightcone, the hosts break down the rise of AI coding agents, "tokenmaxxing", and the emerging workflows behind tools like Claude Code and OpenClaw. They discuss why AI systems today feel less like productivity tools and more like collaborators, why the future of AI should be personal and user-controlled, and how founders are starting to build software in completely new ways. ▶️ Tune in on our YouTube or at the link in bio.

Most AI chips are designed for “prompt in, response out.” Agents don’t work that way. They loop, branch, and hold context across dozens of steps, and current GPUs hit 30–40% utilization because of it. That gap is where purpose-built silicon wins. Apply to YC Summer 2026 at ycombinator.com/apply.

AI has collapsed the cost of producing software by 10–100x, and the moat that once protected legacy SaaS, millions of lines of code built over decades, is gone. That’s bad news for incumbents and great news for startups. Apply to YC Summer 2026 at ycombinator.com/apply.
