Revolutionary tools seldom solve existing problems, instead they give us new abilities or mental modes for dealing with the world. (And sometimes it gives us new _limitations_ as well...) In other words, an automobile is not simply a better horse. A word processor is not just a better typewriter. A printing press isn't just a faster scribe. While there may be some overlap between abilities between the old and the new, and that overlap is often a useful marketing tool, that is usually the least interesting area.
