-beautiful is never being able to blur backgrounds behind a subject because their sensor is too small. Everything is in focus or ugly slightly-blurred noisy backgrounds (rather than creamy)
-don't care that phone focal lengths make human faces look like dogshit (portrait photography is done at 85mm+, iphone is 29mm which isn't even halfway there)
-zoom is suddenly unimportant, never need to take pictures of wild animals at a distance, only the tame house-cat.
Then you already have little reason to not use a phone for all your pictures. But as those 3 things are very important in photography, phone-sized sensors will never, ever be the pro tool.
And slapping a full-frame sensor and giant lens onto the back of a cellphone isn't feasible for a thin pocket gadget, so that'll never change without some unknown new mega-tech of the future.
