Tailwind CSS: The Web Dev Game Changer

Tailwind CSS rose to prominence by applying solid design principles: composition over inheritance (independent utility classes), convention over configuration (smart defaults), and locality of behavior (styles co-located with HTML). These qualities made it predictable and easy to learn. However, those same qualities made it trivially easy for AI tools like GitHub Copilot and ChatGPT to generate Tailwind code, which devastated the business model. Documentation traffic dropped, revenue fell ~80%, and 75% of the engineering team was laid off. The founder shut down the docs site, citing AI's brutal impact. The broader lesson: any developer tool that's easy to learn is also easy for AI to replicate, putting documentation-and-premium-component business models at risk.
