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.
