tl;dr: Frontend educators and luminaries are exiting or pivoting away from the field as AI agents increasingly handle frontend work competently, with React winning out over more ergonomic frameworks simply because "the agents know React." The author argues developer experience improvements (new CSS shorthands, terser syntax, web components) are becoming less relevant since agents don't care about ergonomics, while frontend code is low-risk enough to hand off unsupervised. Possible paths forward for human expertise: guiding architectural decisions (e.g., MPAs over SPAs), making sites agent-friendly, and cleaning up vibe-coded messes.
