It wouldn't be unlearnable if it fits the way the user is already thinking.

A mixed ever-shifting UI can be excellent though. So you've got some tools which consistently interact with UI components, but the UI itself is altered frequently.

Take for example world-building video games like Cities Skylines / Sim City or procedural sandboxes like Minecraft. There are 20-30 consistent buttons (tools) in the game's UX, while the rest of the game is an unbounded ever-shifting UI.

Tools like v0 are a primitive example of what the above is talking about. The UI maintains familiar conventions, but is laid out dynamically based on surrounding context. I'm sure there are still weird edge cases, but for the most part people have no trouble figuring out how to use the output of such tools already.

Like Spotify ugh
