My takeaway from the demo is less that "it's different each time", but more a "it can be different for different users and their styles of operating" - a poweruser can now see a different Settings UI than a basic user, and it can be generated realtime based on the persona context of the user.
Example use case (chosen specifically for tech): An IDE UI that starts basic, and exposes functionality over time as the human developer's skills grow.
