Funny, I was present when this conversation took place. Hearing Gerry Sussman talk was truly inspiring. However, I would somewhat disagree. For sure, the way we program in day to day work has changed, and the curriculum should also touch that. However I think, learning the very fundamentals of computation is essential for a proper system understanding. SICP provides a great way of doing that and the choice of scheme as a minimal, yet powerful language fits to that. I can only recommend everyone to at least read through this great book.
