The fact that articles like this are being written shows how far software design has come. To my mind, that means it’s just starting to show promise.
Good designers have always applied “Product Thinking” to interface design, whether physical or digital. The trouble is, software used to be made by scientists and the World Wide Web was published by everybody and their cat. UX designers emerged relatively late in the process, when technologies had advanced sufficiently to make it possible, and necessary, to actually design an intuitive user experience. Previously, users had to learn each new interface, operating system and graphical paradigm that came along, whether they liked it or not. No wonder whole generations didn’t catch on or keep up.
UX Design doesn’t need a next big thing, it just needs to make technology accessible. It’s the same as it ever was.
