Summary

Dan Shapiro describes building a complete Rust webcam application overnight while sleeping, using his 'trycycle' AI coding methodology with a non-frontier open-source model. Frustrated by Canon's bloated webcam software repeatedly crashing, he tasked an AI agent to rebuild it from scratch in Rust, reusing only the original DLL. What Claude estimated would take 2-3 weeks was delivered in six hours of unattended overnight work for twenty-one cents. The post serves as both a practical demonstration of his Dark Factory approach and an argument that AI-driven development has made the cost and time of building software nearly negligible.

Key Insight

AI coding agents have made software development so cheap and fast that a complete Rust application can be built overnight by a sleeping developer for twenty-one cents using a non-frontier model.
