Inside Devin: The world’s first autonomo...

Lenny Rachitsky
About this episode

Scott Wu is the co-founder and CEO of Cognition, the company behind Devin—the world’s first autonomous AI software engineer. Unlike other AI coding tools, Devin works like an autonomous engineer that you can interact with through Slack, Linear, and GitHub, just like with a remote engineer. With Scott’s background in competitive programming and a previous AI-powered startup, Lunchclub, teaching AI to code has become his ultimate passion.What you’ll learn:

1. How a team of “Devins” are already producing 25% of Cognition’s pull requests, and they are on track to hit 50% by year’s end

2. How each engineer on Cognition’s 15-person engineering team works with about five Devins each

3. How Devin has evolved from a “high school CS student” to a “junior engineer” over the past year

4. Why engineering will shift from “bricklayers” to “architects”

5. Why AI tools will lead to more engineering jobs rather than fewer

6. How Devin creates its own wiki to understand and document complex codebases

7. The eight pivots Cognition went through before landing on their current approach

8. The cultural shifts required to successfully adopt AI engineers
