a) is it really accurate that a smart person can't legitimately learn and be sensitive to life experiences from others or b) why can't they hire people to advise them while still managing the project themselves?
This sounds like a solvable problem by promoting being sympathetic and deferential, rather than replacing people outright from the process simply because they aren't 'from' that group. It's just as likely the people with the life experience don't have the other skills for managing or running a project as well.
Everyone is acting like this project is already a success when it has just launched...Id wait a couple years before calling LeBron a hero.
