I agree, a lot of younger programmers think they have 3 years experience when they've had the same month of experience 36 times.
And this is not a dig against old people per se. But it's the sunk cost fallacy.
If you've only been doing something for 3 years, and it's wrong, it's easier to convince them that it's wrong, vs. if you've been doing something for 20 years, it's a lot harder to convince somebody that they're doing it wrong.
Especially if they've been successful doing things their way for 20 years.
