Isn't that happening already? Half the usual CS curriculum is either math (analysis, linear algebra, numerical methods) or math in anything but name (computability theory, complexity theory). There's a lot of very legitimate criticism of academia, but most of the times someone goes "academia is stupid, we should do X" it turns out X is either:
- something we've been doing since forever
- the latest trend that can be picked up just-in-time if you'll ever need it
Parent comment is literally praising an experience they had in higher education, but your only takeaway is that it must be facile ridicule of academia.
Well, at more elite schools at least, the general assumption is that programming is mostly something you pick up on your own. It's not CS. Some folks will disagree of course but I think that's the reality. I took an MIT Intro to Algorithms/CS MOOC course a few years back out of curiosity and there was a Python book associated with the course but you were mostly on your own with it.
I've worked in education in some form or another for my entire career. When I was in teacher education in college . . . some number of decades ago . . . the number one topic of conversation and topic that most of my classes were based around was how to teach critical thinking, effective reasoning, and problem solving. Methods classes were almost exclusively based on those three things.
Times have not changed. This is still the focus of teacher prep programs.
