MIT is unusual in that it combines EE and CS into one department. While SICP may be the best intro to CS ever written, that does not mean it is the best possible choice for a combined CS/EE program.
Did your friends say what it was they hated about Scheme after taking that class? I can see where people might make an association between the language and the difficult tasks they were being asked to perform with it.
This is probably a personality thing. Many of my friends at MIT loved 6.001/SICP/Scheme and most of them at least respected it. Personally the class rewired my mind in fundamental ways and I appreciate that.
That said I trust the folks running the Course VI department. I have not looked into the specifics of the new program but I suspect it is a fine program.
Who else is using Scheme for the intro course? Is it just Berkeley now? BTW, anyone know what Stanford uses for the intro sequence? Just kinda curious.
