The people who have fallen behind the most are the ones who don’t realize they’ve fallen behind. “What you know you don’t know, versus what you don’t know you don’t know” and all that. They are also the people least open to catching up when the opportunity presents itself; if you think best practices haven’t changed since you were initially trained, why would you even entertain any information that contradicts what you initially learned? Part of this is ego, as it would require admitting that you’ve been doing it wrong this whole time (so instead these people keep doing it wrong as some kind of sunk cost fallacy).
Millennial here. My impression is we’re the largest generation on this platform, but I could be wrong.
