Perhaps We Only Need Five Computers

In the very early days of computing there were a number of predictions about how many computers the world needed. The predictions ranged from 5 to 20. Clearly these were a little out, here’s an actual estimate. However, Nicholas Carr has pointed out that some of these predictions may be true (in a sense). Chapter 7 of the book describes the cloud computing concept where many computers combine together in order to function as a single computer using the Internet as a communication medium.  What Carr points out is that there may only be five in the future, each run by a corporation, government or some other organisation. This chimes in with the vision that Jonathan Zittrain has in his book The Future of the Internet and Tim Wu’s book The Master Switch.
