One counterexample: my grad school linguistics professor, an internationally recognized scholar across several languages, credited the DoD Language school at Monterrey CA as having been just amazing, and who went back to teach for decades in a top five ranked US university, not only linguists but engineering kids like me. He was the same age as my dad so had the avuncular thing going, was personable, but most of all inspiring to decades of students to look outside their curricula. Sometimes what sounds like up a creek turns out to be an unpredictable kick ass river, I guess.
