Obviously, there's plenty of bias here given the source, but I think on balance it either hinted at or laid out a lot of the issues we know about the state of 9-5 employment, most notably in the U.S, fairly well:
-Lack of control over schedule/location
-Lack of growth paths at many companies
-Lack of leverage/Inputs match outputs almost 1:1 (sell time, make a dollar)
-Not getting rewarded for the value you bring to a job; instead that value accruing mostly to people above you
-That feeling of being merely a line on a spreadsheet
Over time, I've learned that for some people, articles like this will really resonate and shake them to their core. (I happen to be in that category but I've experienced enough in previous entrepreneurial ventures for this enthusiasm to be tempered a little bit with reality every time I read things like this).
Others will recoil seeing this, their first instinct going to the (very real) risks in leaving that system and conclude they're far more comfortable optimizing for the familiar.
Both reactions are perfectly OK. There's no wrong or right answer. It's just what connects with you, as a person.
The key is to understand that, either way, you're in charge of your career, regardless of what kind of professional setup suits you best and makes you happiest.
