Are AI‑generated UI designs good enough for production apps?

I continue building UI pages for my email marketing platform using AI, and I wondered if AI‑generated UI designs are good enough for production apps?

They seem to work great on mobile devices and desktop screens. They load fast. They behave normally. I’m personally perfectly fine and happy to use them in production, but what is your opinion? Am I missing something? Should I be worried about using them in production?

To build UI I use Lovable and Google Stitch. I go feature by feature, and for each feature I create a separate Git branch. This way I’m more careful that one update does not break my entire website.

P.S. The attached screenshot is a work‑in‑progress design that I created using Google Stitch for the Email Automation and Sequencing feature.
