How many people with an actual job role, with job role duties, are going to have a job role that's as interesting and engaging as that special operations task force though? A job that engages will get the best out of people, whether they are internally or externally motivated. Even internally motivated people will stop living up to their potential if their job role doesn't change to keep them engaged. The problem might not be the people, the problem might be the roles. Yet Musk, like most others, is firing the people instead of firing the roles.
