Evolution of the Operating System
In Nature, we believe that diversity of living things allows the survival of the fittest to gradually change the ecosystem as conditions change. This is happening in information technology. Moore’s Law and corollaries which describe the production of every more powerful, compact and inexpensive devices in display, computation, storage, memory and networking are relentlessly allowing smaller and cheaper computers to do amazing things for people. There is no longer
* a need to have a large heavy expensive box nearby for computation,
* a need for cabling to tie computing devices to the network,
* a need to have any single stack of software to do everything, and
* a need to use a particular kind of processor in IT.
