These days we have to expect many projects will have them. It's really a question of how responsibly and carefully AI is used. Some people just throw in their requirements, have the AI spit out code, do a cursory check to see if it seems to work, and that's it. Other people take responsibility for the architecture and the code quality, using AI in a focused way and reviewing the results carefully. I'd look at the quality of the architecture and code before judging. I confess I have not done that yet with this one; I just thought it sounded potentially interesting.
There are quite a few ways to write web applications with Rust these days, and while this sounds like it has potential, I'd still pick frameworks that are a little more mature for my own projects.
