"Life long learning" is a catch phrase.

Most people, even most professionals don't do it. They rise to a certain level then delegate the technical stuff down. Technical skill development tops out at abou 10-15 years in and then people either know everything they're likely to know for the duration of their careers or they transition to management and forget all that tech stuff.

I'm an engineer and one of the few who, at 17 years in, is still trying to develop more skill. I've worked at 6 firms in that time and a few more as an intern before graduating college.

Just as with religion, a doctrine is learned and that doctrine, once learned, is only very rarely challenged. The same problems get addressed the sams way over and over. The weird stuff gets sent to the 5 percenter who questions doctrine and remembers there are ways to solve problems outside of the standard proscribed method.

Most people are NPCs. Most professionals are NPCs. Most doctors are NPCs.
