Devin 2.0 and the Future of SWE - Scott Wu, Cognition
Jul 25, 2025 · 16:13
Scott Wu of Cognition AI describes an AI 'Moore's Law' for coding agents, with capability doubling every 70 days, propelling Devin from simple migrations to autonomous project work. He traces Devin's evolution through tiers: first repetitive migrations using Playbooks for instruction-following, then isolated bugs with VM snapshots, then multi-file changes with codebase intelligence, and finally backlog killing with self-testing. Each tier required solving different bottlenecks—memory, language server integration, iterative planning, and confidence calibration. Wu argues that the interface and key capabilities shift every 2-3 months, and predicts another 16-64x improvement in the next year.
