WHY AI SUCKS AT FRONT END

Summary from the TLDR Marketing newsletter

AI tools excel at scaffolding generic UI components, migrating design tokens, and outlining features. However, they fall apart when front-end work requires pixel precision or bespoke interactions. The core issue is that LLMs trained on common web patterns cannot see rendered output, struggle with math-heavy layout calculations, and have no control over the chaotic browser environment where HTML and CSS actually execute. Scroll-driven animations and complex component states are particularly weak spots. The more complex a component becomes, the slower and less reliable AI assistance gets.
