My thoughts exactly. I was writing an article about this idea, but it got scrapped. With big data and ubiquitous artificial intelligence, interaction with technology will become perfectly frictionless. There will be as much "interface" as you need (wether it's a graphical, voice or whatever interface, all we can do is speculate), exactly when you need it, it will be specifically designed for your use — and it will go away when the task at hand is done. This is a very near future, so strap in and get ready.
