I can tell you where he went wrong: While you are still in a "stable" job, read job descriptions in your area of expertise and if you see a new skill start to pop up that you don't have, learn it. If you're in IT for example, Python is hot with no signs of cooling down. An IT person that doesn't have Python skills is just begging to be sidelined. One reason I'm so annoyed with women in the workplace is that so may of them are posers. Ask them tough technical questions and they fall to pieces. Of course drawing such conclusions isn't "HR-safe", so you just lament posers, which has the same effect, but passes muster under scrutiny for the "cultural Marxism" police.
