Most really interesting and disruptive inventions are at least partially accidental. Ideas rarely spring fully formed; instead they appear through cross-fertilization, recombination and serendipity. Once the idea is there, we invent whatever models and languages are necessary to describe and implement it. That process can be comprehensive and all-at-once but more often is iterative and progressive. Even radical innovations that seem to spring fully formed did so after long gestation outside public view.
