Computers make it easier to do a lot of things, but most of the things they make it easier to do don't need to be done. 

A computer lets you make more mistakes faster than any invention in human history - with the possible exceptions of handguns and tequila  

If automobiles had followed the same development cycle as the computer, a Rolls-Royce would today cost $100, get a million miles per gallon, and explode once a year, killing everyone inside.
