Lisp and Smalltalk are dead: It’s C all the way down 17 years ago
I took CS 2340 in Smalltalk a year ago at Georgia Tech. I think most people in the class disliked the IDE more than Smalltalk itself. Visual works was absolutely unusable on a mac and the Windows version certainly had its quirks. That, coupled with the fact that Smalltalk isn't used too often anymore led to students being really unsatisfied with the language.
I do think that the language needed to be changed for that class. The College of Computing is not entirely C though; I did learn lisp for an Artificial intelligence class, but not all students are required to take it.
