Designing in Words: How AI Turned UX Designers Into Their Own Frontend Engineers

The design review went perfectly. You handed off a Figma file that was pixel-perfect: the right spacing, the right micro-interactions, the hover states, all of it. Three weeks later, the thing that shipped looked like it was built from memory by someone who saw your design once in a dream. Sound familiar?

That story has been playing on loop for the entire history of digital product design. The designer creates. The developer interprets. Something gets lost, always. Sometimes a lot. And the designer files it under “developer error” and moves on to the next project.

Spec-Driven Development: The End of Amateur Vibe Coding and the Dawn of Systems Engineering for UX

The concept of [[Vibe Coding]] is appealing. You write in natural language, AI spits out code, and you have a prototype in minutes. It works perfectly for a 100-line script. Try scaling that to a real product, and the system collapses.

I sat down with Ryan Edge to break down exactly how he’s using [[AI]] agents to build complex software. The consensus is clear: relying on chat interfaces to code has a glass ceiling. You lose context, the AI hallucinates, overwrites existing logic, and you end up doing manual work to correct a robot.
