Edsger Dijkstra Computer Quotations

The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.

When we had no computers, we had no programming problem either. When we had a few computers, we had a mild programming problem. Confronted with machines a million times as powerful, we are faced with a gigantic programming problem.

Computer science has as much to do with computers as astronomy has to do with telescopes.

If we wish to count lines of code, we should not regard them as 'lines produced' but as 'lines spent.'

It used to be the program's purpose to instruct our computers; it became the computer's purpose to execute our programs.
