I agree to a large extent, but not 100%. Here is why.

You correctly said that Physics majors do not study which details of bridge building. Indeed this is part of a different major (Civil Engineering, I suppose).

In contrast, Computer Science is a very broad discipline. Large portions of it are science; large portions are engineering (or similar to engineering, if we exclude Computer Engineering per se). A good student, or a student with a good mentor, should be able to choose a more theoretical (scientific) or more practical (engineering) path and work on the curriculum accordingly. I understand that it is not always possible (in some places, for example, students cannot choose classes), but at least a student should be able to choose where to focus.

A small point about "picking languages on their own". I think basics of languages can be taught to freshmen, at least selectively, to help those students who may be lacking in previous exposure to computers in high school. (Depending on the university, this may or may not be an issue.) Teaching basics of C or Java or, I don't know, Python, whatever, this way does not turn a university in a Java school or anything like that. Indeed it may be as useful as remedial classes in calculus.
