> There's such a problem with immaturity in tech. It's frustrating because it creates barriers to learning from others. No self-respecting person is going to want to learn from someone who has a "holier than thou" or "I'm a rockstar" mindset.

You wouldn't consider it to be immature to not do the right thing just because it was communicated in an unpleasant way that a 'self-respecting person' should have disdain for? I'm not talking about this particular article or defending immaturity, - I just don't see how your position is any better; more so it's just as unhumble as the 'rockstar position' since you would apparently be willing to write worse code just to avoid learning from someone that's an asshole.
