AI Coding Agents Are Breaking Big Codebases — Dan Adler, Sourcegraph
AI coding agents are flooding large legacy codebases with unreviable code, risking systemic collapse
“A tsunami of code is coming at you. It's creeping up on your codebase and all your engineers trying to just stay afloat.”
Sourcegraph CEO Dan Adler argues that AI coding agents are exacerbating the maintainability crisis in large enterprise codebases, where 72% of software workers manage decades-old, multi-thousand-repository systems. The speed of AI-generated code is outpacing engineers' ability to safely review it, and the tools being built to check AI code only add more automation to an already fragile stack. Adler warns these massive legacy codebases — the invisible infrastructure of global finance, logistics, and utilities — are beginning to collapse under the weight.
