Let me try to get this straight: Lisp is a language for describing algorithms. This was JohnMcCarthy's original purpose, anyway: to build something more convenient than a Turing machine. Lisp is not about file, socket or GUI programming - Lisp is about expressive power. (For example, you can design multiple object systems for Lisp, in Lisp. Or implement the now-fashionable AOP. Or do arbitrary transformations on parsed source code.) If you don't value expressive power, Lisp ain't for you. I, personally, would prefer Lisp to not become mainstream: this would necessarily involve a dumbing down. -- VladimirSlepnev

Humans differ from animals to the degree that they are not merely an end result of their conditioning, but are able to reflect on their experiences and strategies, and apply insight to make changes in the way they live to modify the outcome. -- SlideTrombone (comment on "Programming can ruin your life")

If you can’t explain it simply, you don’t understand it well enough. ~Albert Einstein

When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down ‘happy’. They told me I didn’t understand the assignment, and I told them they didn’t understand life. –John Lennon

Winning isn’t everything, but wanting to win is. –Vince Lombardi
