“People always fear change.  People feared electricity when it was invented, didn’t they?  People feared coal, they feared gas-powered engines.  There will always be ignorance, and ignorance leads to fear.  But with time, people will come to accept their silicon masters.”

As Bill Gates once warned, computers have indeed become our silicon masters, pervading nearly every aspect of our modern lives.  As a result, some of the greatest minds of our time have pondered the significance of computers and software on the human condition.  Following are 101 great quotes about computers, with an emphasis on programming, since after all this is a software development site.
