There is the desire of a consumer society to have no learning curves. This tends to result in very dumbed-down products that are easy to get started on, but are generally worthless and/or debilitating. We can contrast this with technologies that do have learning curves, but pay off well and allow users to become experts (for example, musical instruments, writing, bicycles, etc. and to a lesser extent automobiles). [Douglas] Engelbart’s interface required some learning but it paid off with speed of giving commands and efficiency in navigation and editing. People objected, and laughed when Doug told them that users of the future would spend many hours a day at their screens and they should have extremely efficient UIs they could learn to be skilled in.
