Web Standards and Front-End Development

AI-Generated Code & Front-End DX

[It] can take years of Interop work to get a feature to the point it becomes “Baseline newly-available”. […] If it’s not in the LLM training data, it doesn’t exist.
Developer experience features (syntactic sugar, convenience APIs) are competing against established […] patterns in LLM training data

Dead framework theory

AI-Generated Code & Accessibility

The [...] results suggest that objective error count is too high to rely on LLM technology at all in digital accessibility work, even under explicit expert guidance.

AI-Generated Code & Accessibility

LLMs excel at addressing basic accessibility requirements but struggle with complex accessibility requirements, particularly ARIA-related attributes, performing worse than human developers.
Advanced prompting techniques consistently generate code with lower accessibility issues than human-written code [but with] inherent limitations in addressing accessibility through prompting alone.
