It swings both ways though. I've seen plenty of older engineers dismiss the "new guys" effort and claim that everything had to be custom written, because there's no way a common framework like Django could cover their use case. The same type of engineer has never once worked with a common framework though, so they don't know what's included nowadays.
Turns out it's a lot easier to build on top of a common framework than do everything from scratch.
Sure I had an older dev do bit masking for a list of 3 options in javascript because he was used to old terminals.
Its something different coming in and changing things here and there but rewriting the hole thing on a weekend is something different.
