Some 20+ years from now iPhones will become "obsolete". Most of the next generation to come after Z will either be wearing wifi VR headsets or having neural implants installed in their heads to hook their brains to the "internet of things". While this is dystopian and cheesy AF and while many people today would rather die than live that way, most future normies will just adapt to it and accept it no matter how shitty the experience. At that time you'll have some of generation Z anons who refuse to adapt, staying disgruntled while flipping around Tik Tok on their 12 year old outdated smartphones waiting for the next video to be uploaded.
