The Codebase Is No Longer a Moat

The codebase is no longer a moat For the last two decades, the software industry believed a simple rule: keep your code closed and competitors cannot catch you. A rule built on fear, and on a world where writing software required armies of engineers and thousands of hours. AI has rewritten those economics. A small team with strong taste now ships at a pace that used to require a company of fifty. Tools like Cursor, Devin, Zed, Claude Code, GitButler, and Warp generate features in hours instead of weeks — and can refactor entire systems in a single morning. The real advantages now are taste, execution, and trust.
