people say that every time apple makes changes to their GUIs. so i'll bet you a macbook that, in time, the current look will become comfortable for (almost) everyone. and someone will say the same thing you're saying now when we see the next major shift in apple GUIs...
I entirely agree with the summation that people get annoyed by GUI changes and then get used to them
in this case however, they have made the UI objectively less user friendly in order to shoehorn in a design language meant for a completely different interface
this isn't a new take on keyboard/pointer interface, this is slapping a touch/spatial interface on top of such purely for the sake af aesthetics
