A person with the job title "senior developer" has, what, 3-5 years of full-time work experience? So instead of being 21 and bushy-tailed, they're 24-26 and only slightly less bushy-tailed. They're still working through the maladies of youth, like absolute opinions, rabbit-holing, perfectionism, zealotry, and over-identifying with their work. A young person might need 10 years or more to develop a balance of caring and DGAF skills. And some people stay insufferable forever!
