Apple has been converting the UI of the Mac into something like that of iOS devices. Vertical alert windows and fake camera cutouts on the top of the screen are obvious examples. There is no purpose for that other than to accommodate the eventual merging of iOS and macOS. Long ago now, Apple absorbed Apple's macOS developer team into the iOS team. As a independent Mac developer it has been clear to me that macOS development is falling well behind iOS development. I don't think it's going to be a matter of adding a touch screen. After it happens, I don't think there will be much left the the Macintosh.
