I tend to agree with most points. I always credit my undergraduate CS education with teaching me about how to think about a variety of computational problems using a variety of languages as lenses. I actually think that is why I've been able to succeed in a number of different development roles (Web Developer, Mobile Developer, Reverse Engineer). If I had had multiple semesters of learning only language/framework-X features, I think I would have been worse off for it.

That being said, it did take me a while to appreciate that this was what my education gave me and obviously, no approach works for everyone.
