After Code Gen: What Graphite Is Building for the Post-AI Dev Stack | Greg Foster

The incredible velocity of AI coding tools has shifted the critical bottleneck in software development from code generation to code reviews. Greg Foster, Co-Founder & CTO of Graphite, joins the conversation to explore this new reality, outlining the three waves of AI that are leading to autonomous agents spawning pull requests in the background.

The incredible velocity of AI coding tools has shifted the critical bottleneck in software development from code generation to code reviews. 

Greg Foster, Co-Founder & CTO of Graphite, joins the conversation to explore this new reality, outlining the three waves of AI that are leading to autonomous agents spawning pull requests in the background. He argues that as AI automates the "inner loop" of writing code, the human-centric "outer loop"—reviewing, merging, and deploying—is now under immense pressure, demanding a complete rethinking of our tools and processes.

The conversation then gets tactical, with Greg detailing how a technique called "stacking" can break down large code changes into manageable units for both humans and AI. He also identifies an emerging hiring gap where experienced engineers with strong architectural context are becoming "lethal" with AI tools. This episode is an essential guide to navigating the new bottlenecks in software development and understanding the skills that will define the next generation of high-impact engineers.

Greg Foster is the co-founder and CTO of Graphite, a code review platform used by teams like Cursor, Replit, and Snowflake. On Chain of Thought he argued that AI coding tools have shifted the bottleneck from writing code to reviewing it, and explained how "stacking" breaks large changes into reviewable pieces.
