I’m sorry you’ve had some bad experiences but not everyone is like that.

However it’s also misguided to assume that specialities don’t exist. You can have infrastructure guys, developers, security folk; and there will be overlap between each role but it’s impossible to be the master of each trade.

I agree that arrogance is an unpleasant trait but arrogance can take many forms, rudeness to colleagues, or over assuming ones own technical capabilities in adjacent fields.
