First, depends on definition of "College" and "University" that differs from country to country.
But overall, value of University education to improve your employability and skillset I think is being questioned by both employers and employees.
1. Some "Blue Collar" skills may withstand the test of automation better than many "White Collar" skills - e.g. I anticipate needing an electrician, contractor, plumber for the next few decades; but hopefully accountant, lawyer, travel agent etc less and less.
2. For "White Collar" skills, well... I went to ComSci university and it's not that it brought no value - but given the time, money, effort and commitment, it was very very low value proposition. I spent more time satisfying bureaucratic obligations and navigating the needlessly complex machinery than actually learning. (note I wasn't the one going to university for some "Party / Social Experience" - I found many better, more flexible methods than that:).
Not going to university is not necessarily the same thing as not wanting to learn and educate and acquire skills. And there is a whole spectrum today between free online education (random Youtube videos, manuals, free university courses etc), bootcamps, practically oriented post-secondary education, and then university.
Bottom line: I have two young kids, I want them to succeed, and I want them to be educated - and I don't know if traditional university is something I will encourage them to consider 10 years from now.
I honestly don't know however how that translates into a gender gap discussed in the article though; and article doesn't really provide a satisfying answer either :-/
