Yeah, I think so... It's not so much the idea of the raw number of student who go to those schools, but the thought that other schools look toward them for some direction. If I recall that article from the retired teacher from Berkeley correctly, he used to help other teachers teach SICP and Scheme.
I'm going on the assumption that there is some feedback loop going on here, and that without people actually being exposed to Lisp in school, then there is probably going to be less people even aware of Lisp's existence. I wonder how many schools will drop Lisp completely now after MIT and Berkeley dropped it.
Now, if Clojure looked like Python, I bet dollars to donuts it would be the number one language in use already.
Also, from what I've seen of Rich Hickey's presentations and speeches he's doing a pretty good job making the case for immutability and functional programming.
