Ruby on Rails creator David Heinemeier Hansson has declared pencils down on manual programming, the article reports.

He said his latest project, a system named Omarchy, was built entirely by AI agents.

The article says AI sometimes struggled with existing platforms like Basecamp during development.

Despite those hurdles, the automated agents completed the entire Omarchy codebase.

The piece says the experiment suggests AI struggles with legacy systems but excels at brand-new projects.

Hansson's new initiatives have also started using Rust rather than relying only on Ruby.

The announcement has sparked debate about the future of human programmers, including junior developers.

Critics warn heavy AI reliance could introduce hidden vulnerabilities without careful human code review.

Developers will watch Omarchy's long-term stability as a test case for fully AI-generated software.
