Even if the author realizes that, it doesn't change the fact that what they are doing is mostly admin and management, not science.
I left academia--more-or-less--after doing several post-docs and taking a hard look at an employment landscape where colleagues who were at least as good as me were taking offers from second- or third-teir institutions because that was all that was available. I knew some of them were profoundly lonely and struggling in those positions, outside of the charmed circle of the top teir they had comfortably inhabited for so long.
Beyond that, there was the realization that unlike the profs who trained my generation, people my age pursuing tenure were rarely getting into the lab. They couldn't afford to. They had to stay relentlessly on the track of paper and grant generation, as well as committee work, if they wanted to succeed.
I would be a really bad fit in that job. I got into science because I love the hands-on act of "disturbing the universe", in Freeman Dyson's memorable phrase, and even in the improbable event that I landed a tenure-track job (improbable in part because as a post-doc I tended to work on problems that interested me, rather than ones that would lead to lots of publications) I would end up spending most of my time doing stuff I wasn't very good at and didn't much enjoy.
It's one thing to say that "every job has a certain amount of work involved" (there are always less appealing things you have to do in the name of the stuff you enjoy) but when a job is mostly stuff you aren't suited for, it's not a good idea to pursue it.
This is the fundamental problem of modern academia: researchers are getting shunted into managers and administrators as soon as they get on tenure track. While the age they make the transition to tenure track is going up, the length of active research careers is going down. Hands-on research scientists who are active over the full length of their career are almost always in some kind of permanent research associate position, free from the vagaries of tenure and promotion. They are the people most of us who go into the sciences want to be, but the positions available for them are few and far between.
We need serious, genuine academic reform so that there are more positions available for career scientists who do science, rather than careerists who transition to managers and administrators the moment they become assistant professors.
