I may only be a few years out of university, but over the last couple years I've learned that what I studied in university falls into three categories:
1) Incredibly out of date.
2) Far newer than what my job requires me to use.
3) Existing in some ideal world that matches nothing anyone actually created or uses in industry.
And yes, it's possible (and not rare at all) for both (1) AND (2) to be true at the same time.
All of above - at the same time - ends up in the middle of Gartner's hype cycles: a solution has been found 20 years ago and people are searching for problem it solves ever since.
