> But yes, it would be a tragedy if the better, more revolutionary way of working was discarded for an incrementally better version of what we are used to.
This tragedy is common occurrence with incremental ideas.
Compared to the revolutionary, incremental ideas have an unfair advantage. They are way easier to talk about, way easier to imagine, way easier to implement, and way easier to sell. They capture the market, and before long, too many people's lives will depend on them that no one would dare even propose doing things differently.
This has happened time and time again. QWERTY is a nice example:
> The top row of alphabetic keys of the standard typewriter reads QWERTY. For me this symbolizes the way in which technology can all too often serve not as a force for progress but for keeping things stuck. The QWERTY arrangement has no rational explanation, only a historical one. It was introduced in response to a problem in the early days of the typewriter: The keys used to jam. The idea was to minimize the collision problem by separating those keys that followed one another frequently. Just a few years later, general improvements in the technology removed the jamming problem, but QWERTY stuck. Once adopted, it resulted in many millions of typewriters and a method (indeed a full-blown curriculum) for learning typing. The social cost of change (for example, putting the most used keys together on the keyboard) mounted with the vested interest created by the fact that so many fingers now knew how to follow the QWERTY keyboard. QWERTY has stayed on despite the existence of other, more "rational" systems. On the other hand, if you talk to people about the QWERTY arrangement they will justify it by "objective" criteria. They will tell you that it "optimizes this" or it "minimizes that." Although these justifications have no rational foundation, they illustrate a process, a social process, of myth construction that allows us to build a justification for primitivity into any system. And I think that we are well on the road to doing exactly the same thing with the computer. We are in the process of digging ourselves into an anachronism by preserving practices that have no rational basis beyond their historical roots in an earlier period of technological and theoretical development. – Seymour Papert, Mindstorms
That's why I believe we should be more evangelical in promoting revolutionary ideas (from the blue plane), and more quick to point out incremental ideas (the pink plane).
