In this episode of The Breakdown, Tom and Dave are joined by fellow YC General Partner Pete Koomen to lay out a new vision for how AI should actually work: not as a chatbot bolted onto legacy software, but as a customizable tool that helps people offload the work they don't want to do. From editable system prompts to agents that act more like collaborators, they dig into what it means to build AI-native software—and why the future belongs to products that let users teach machines how to think.

Coding agents are no longer a distant idea—they're already starting to reshape how we work. YC's Tom Blomfield and David Lieb discuss how AI coding tools are transforming software development, why small, high-agency teams will be able to do what once took armies of engineers, and why there's never been a better time to start something new. They explore the bigger picture too: a future where there's abundance, knowledge work becomes more accessible, and founders have more leverage than ever before. If you're thinking about building, there's no better moment than right now.

AI can't yet one-shot an entire product—but with the rise of vibe coding, it's getting close.
