The Story Behind This Design
Every programmer remembers the first time they saw package.json.
Every AI coding assistant assumes you already know what JSON is.
This shirt captures that exact moment—when modern development moves faster than your understanding, and the only reasonable question is:
Who is JSON?
Whether you're learning through Claude Code, Cursor, GitHub Copilot, or your favorite coding assistant, this design celebrates the beautiful confusion of modern software development.
