I disagree, because most of the frontend work I’ve been involved with over the past 10 years or so isn’t just blindly implementing mockups. Actual UI engineering work usually involves making the feature a logical reality. Product and UX have a great ideas, but they’re not engineers and it usually takes a lot of work to make these ideas match the reality of the domain, making things consistent with UI patterns, existing components, web standards, etc.

I’m honestly not worried about AI being the programmer for UX people, that’s for sure. I think creating mockups are a bigger target for AI.

Also, this work is usually the best starting point for a meaningful domain API, and helps drive the backend as well.
