You a senior developer or have senior developers work for you? This video is about the career path of senior developers (to technical lead, architect, staff engineer, principal, etc).
I think people get the wrong mental models of what a career path of a senior developer could be or what the roles are, especially as the team size and organization size grows beyond 1 supervisor-1 (junior) developer.
