Of course not everyone is autodidactic so the path is not for everyone, but it is indeed quite possible to acquire this kind of knowledge/humanity outside of the university structure.
Alternatively: everyone should read the classics.
Also sometimes it's just cool to have the guy who wrote the textbook be your professor.
- Someone who knows those books to explain and lead discussions about them.
- A place to hold those meetings.
- Some kind of accountability for actually doing the readings, writing the papers, and internalizing some understanding.
That costs a little more than $1.50 but it has no right to cost $150k. It's not like graduate student wages are expensive.
When my children get old enough I hope to attend with them. I had the great fortune to experience a Great Books program for 2-3 years in high school (a pet project of a teacher who fought tooth and nail to fund that class) and consider it a formative experience.
Just to point out that much like working at a high level in tech, a degree is actually not a hard pre-requisite to having an understanding of the humanities, ethics, etc.
Also just like STEM, many will absolutely benefit from the structure of a university setting.
I just couldn’t resist the Good Will Hunting quote.
Those classes covered things which I have never encountered in my _trade_, but which formatively affected my views on how one should treat others (or treat oneself). I feel like the stereotypical "liberal arts" education, in which one studies things that are not just focused on your trade, has an intrinsic value which is hard to articulate.
