Could AI-Powered UI Replace Guesswork in Software Feature Development?

A software engineer with over 20 years of experience is exploring a hybrid UI pattern where an AI layer works alongside traditional interfaces to handle requests the static UI cannot fulfill. Rather than replacing conventional navigation, the AI activates only when users hit a ceiling, generating structured data that selects from pre-built components instead of producing arbitrary code. The approach draws on Vercel's AI SDK Generative UI, open-sourced around 2024, as its most concrete production implementation. The author argues that industry data — showing 64–80% of software features go largely unused — points to a fundamental feedback gap between user needs and product roadmaps. The core proposition is that LLM inference costs, though higher than standard database queries, may be justified if each unresolved user request becomes a labeled signal guiding future engineering investment.
