SICP

Hello /sicp/.

I understand that the High Neckbeard Council wants me to read SICP posthaste. But can anyone tell me WHY I should invest my time in reading it? Honest question. What does it offer me, as a lowly PHPfag?

It offers you a chance to become something other than a lowly PHPfag (and not a Ctard either). Do you want to be a good programmer?
