Programming is the act of "describing" a computation to a computing machine. In the past people used gears and levers to do that for mechanical computers. The way of describing computation can exist in many forms, like, formulas in excel sheet or using timeline to describe an animation or using C to build a device driver. All these ways have their own particular context to be useful. So, it doesn't make sense that in future we will have "one particular way" of describing computations.
