Wouldn't things be much simpler if every computer system was built on the platform, ran the same operating system, and every program was written in the same programming language? The biggest problem, however, is that in a world where every computer system runs the same software, the same version of the same operating system, on the same hardware, every computer system has exactly the same bugs and security weaknesses. Diversity, in the technological world, exists in part because specialization makes systems more efficient, which allows the exploitation of new market niches.
