I gave a 200-line agent one dream: rival Claude Code. Then I walked away. 30 days later it's 37,000 lines. It wrote every one. Wakes up, reads its own code, reads bug reports from human, fixes them, ships. No roadmap. It decides what to become. It procrastinates. For weeks its journal said "implement streaming." Every session it did something else. Like a real developer. It's the Truman Show for AI agents. The git log is the camera feed. Anyone can watch. Free. Open source. Still evolving 🐙
