The issue I have with it is that when I was in college, one of the few things I knew least about is what I wanted to do with my life.
I don't know about this. I run a team of ML engineers, and the ones who require being told what to do in order to be productive are simply worth less to the team. Sure, the scope of work is very specific (often limited to the teams purpose/mission), but autonomy is very much sought after and rewarded where I work. I simply don't want to work on a team where I, as the boss, am the sole person responsible for finding high leverage problems to solve, and have to then package the work then assign it.
I don't agree with your framing. Yes, people vary on how much autonomy they have in their job, but your life is still yours to live. A big part of being an adult is getting to make choices you didn't have as a kid.
Even if your job is very rote, you can still try to find other jobs, or move to a new place, or whatever.
Many people don't exploit the autonomy they have because they don't have the mindset that they can make choices. Instead they do everything they can let other people make choices for them. I beleithr author is encouraging the mindset of making the most of whatever autonomy you do have.
I’ll have to inform the 50+% of math PhD’s I graduated with that now work in tech…
