The mythical convertible iPad Pro "docking" to a "MBP Base" to use it as a touchscreen. ;)

I like the fact that a number of iPad and iPhone apps now run on macOS without a simulator or any ceremony. While they are touch-optimized, they're easy enough to use with a pointing device. The gotcha to such mythical OS convergence is the inverse is untrue since a desktop UI is unusable 1:1 on a tablet with the coarser granularity of tapping and less keyboard access.

Perhaps OS-level AI in the future will be able to automatically follow design guidelines and UX rules and generate a usable UI (Storyboards or such View parts) on any platform given a description of data, its importance, and a description of what it should try to look like.
