Don't worry about what anybody else is going to do. The best way to predict the future is to invent it.--Alan Kay
Premature optimization is the root of all evil (or at least most of it) in programming.-- Donald Knuth
Lisp has jokingly been called "the most intelligent way to misuse a computer". I think that description is a great compliment because it transmits the full flavor of liberation: it has assisted a number of our most gifted fellow humans in thinking previously impossible thoughts.-- Edsger Dijkstra

dapting old programs to fit new machines usually means adapting new machines to behave like old ones.-- Alan J. Perlis 
A little learning is a dangerous thing.-- Alexander Pope
Computer science education cannot make anybody an expert programmer any more than studying brushes and pigment can make somebody an expert painter.-- Eric Raymond
Einstein argued that there must be simplified explanations of nature, because God is not capricious or arbitrary.-- Frederick P. Brooks
Students should be evaluated on how well they can achieve the goals they strived to achieve within a realistic context. Students need to learn to do things, not know things.-- Roger Schank
