Do Component Libraries Still Matter in the Age of AI?

AI code generation tools don't eliminate the need for component libraries — they work better together. Six reasons are presented for why component libraries remain valuable even in an AI-assisted workflow: they provide rich training data and documentation for AI models, have accessibility built in by default, reduce the amount of code that needs to be generated and maintained, lower token costs by shortening prompts and reducing revision cycles, offer consistent patterns that make human review easier, and help bridge the gap between design and development teams. The post advocates for an integrated approach where AI generates configuration and composition code on top of trusted, well-documented component libraries rather than generating everything from scratch.
