Smartphones obviously aren't just a fashion, touchscreen all the things is a fashion. IT fashions usually work that way - there is an actually useful killer application and suddenly the technologies used by the killer application must be applied to everything. Peer to peer (Napster), Ruby / "static typing sucks, testing is better" (Ruby on Rails), touchscreens (iPhone), JavaScript (one language for client and server), blockchain (bitcoin / getting rich through speculation), deep learning (great solution to SOME problems) - it's a fairly simple pattern. Also, the car industry has looong product cycles, so what you see now is what was hot 5-ish years ago.
