I think the interviewee made a very solid case that there is a hiring gap in the area of experienced specialists. He seemed to think that was the major chunk of the "skill gap" employers complain of.

I have seen that.

On the other hand, he described an army of job-hungry young people striving to get the right education for entry level work... but missing the boat on just the right tech -- again for overly-constrained hiring processes. That does not match my experience: I see students coming out of the educational system -- reputable universities -- with a huge gap in fundamental knowledge.

I fear that universities, colleges, and vocational schools, in their effort to deliver workers with fashionable resumes, are failing to deliver the fundamentals.

Yes, you can teach yourself the fundamentals if you know you need them. But if you've gone through 4-6 years of university under the theory that they are teaching you what you need to know, it may be harder to realize that, in fact, you have learned how to look good, but not how to be good.
