It's an interesting point you bring up. I do agree that the immaturities can be exacerbated by an unwillingness to learn and educate ourselves.
However I do believe that we are (relatively) immature in more ways than just this, certainly in comparison to engineering for example. 60 or so years is not a huge period of time in comparison to many other disciplines, and we see evidence of this time to time (check out this Medium article for some great examples).
Thanks for bringing up these extra points though - it is always interesting to hear other opinions on the matter!
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
