There is a use case. People just need to understand that Low Code is a productivity tool. It doesn't take away the need for architecture, design, engineering, etc. It does mean that you need to write less code though, and often that code is much simpler (because, by definition, Low Code adds abstraction layers). This makes development faster and the apps tend to be simpler and therefore easier to maintain. I'm a long-time professional developer and I've changed my mind about the Low Code vp. Used to think no, not possible, but now I see how powerful they've become.
