When I was in college, I heard that the Computer Science dept would only teach Scheme to keep some students from leveraging prior programming language knowledge & teach from scratch.
It turned me off of pursuing CS. I ended up using $matlab$ in college, then (self-taught) FORTRAN once I got into grad school and beyond. And now I have to use python or R to communicate w my students.
If Rice CS had taught C, I would have added is as a major.
So mixed feelings.
