Couldn't agree more and there is an age dimension to those personality types. Generally 24 yr olds have a very "I know nothing, tell me what to do, I'm excited" attitude while people with a mountain of experience have opinions of their own and, human nature, frequently are resentful or stubborn about being told to do things that feel like reinventing the wheel or a step backward by people more jr than them who did decide to go into management. But following fads in an ever-improving upward spiral (I'm not one of these people who thinks the industry is going in circles) of productivity and expressiveness is just part of the industry reality. Maybe 28 year olds really are more suited, on average, to that reality? They key thing is, even if that is sometimes true, to judge people individually since of course there are older devs who are totally amazing, creative, and flexible and there are 28 year olds that are completely stubborn, unhappy pains in the ass.
