It’s hard to believe ten years have passed since Steve Jobs first introduced the iPhone. It was a watershed event for our industry, a moment when several newly mature technologies converged and led to a radically better computing experience. I’ve always thought of Jobs’ announcement as a spiritual successor to Doug Engelbart’s 1968 Mother Of All Demos, which introduced the world to mice, bitmapped displays, window systems, hypertext, and more besides. I find both presentations inspirational and rewatch them regularly.
