I've been waiting for this. I want it, everyone wants it. To be honest I think if the right people worked on it, you could code business rules with AI like this:
Users have access to their own posts.
Users are in groups.
Groups have an admin user.
The group admin can edit any post.
(probably a bit underspecified, but you get the point)
I can imagine a world where that could theoretically be converted into a domain model, rest endpoints, GQL service and an authentication system. I literally think the above is possible with today's AI capabilities, it's just no one has released a finished product.
Beyond that, I think AI for front-end is a lot harder, but could probably exist at some point.
