Pluralistic: CARDiac, syntax coloring, view source and vibe code (03 Jul 2026)
Cory Doctorow argues that understanding computers at multiple abstraction levels—from cardboard CARDiac to BASIC code to modern "vibe coding"—builds "legibility" and Fingerspitzengefühl essential for problem-solving, and that automated code tools serve as a funnel for cultivating deeper technical skills.
Background
- **Cory Doctorow** is a prominent Canadian-British author, journalist, and activist known for his work on digital rights, copyright reform, and tech criticism. He writes the long-running blog *Pluralistic*.
- **CARDiac** ("CARDboard Illustrative Aid to Computation") was a 1968 Bell Labs papercraft computer used to teach how computers work at a mechanical level — no electricity, just cardboard tokens and slots.
- **"Vibe coding"** is a recent term for using AI tools (like large language models) to generate code by describing what you want, without needing to understand the code yourself.
- The essay argues that **"legibility"** — being able to see and understand what a system is doing at each layer of abstraction (from cardboard tokens to transistors to source code) — is essential for learning, debugging, and improving technology. Features like **View Source** in web browsers once gave everyone that transparency.
