I used to believe in the use case of projects like these but I think AI is making their case significantly weaker. The idea of "hey, you're a backend dev and can just quickly generate a UI in your own language" is quite a valid one, but these days you spend a a couple hours on ChatGPT and get a pretty decent UI out of it, without needing to really know frontend.

I'm far from being one of those people that's like all in on AI, but I've definitely been super impressed with its abilities to generate basic boilerplate code when you're working on project from scratch.
