28 year old here.
There is actually quite a bit of reassurance in that comment. I'm a full time developer and part-time student. I read through the articles linked above because I'm trying to decide on continuing my studies in the fall after receiving a promotion at work. The return I get from my work projects far outweighs what I've learned in school and I'm getting paid for it!
That comment shares a feeling I _don't_ want to have. If I have any motivation to learn something, why waste it on forced material that may not be relevant to me. I'm leaning towards not taking classes. Instead I can focus on learning technologies to integrate into systems I've built. I can read more for fun (which I was able to do this summer). I can finish that game I've been working minutes at a time for the last few years. I can build that bookshelf that I desperately need, to replace the particle board one that's falling apart in my room.
No hate here. If you're younger than 28 (or not) and you have regrets after reading it, you can still change that path. It might just take a bit more work or motivation that you were putting elsewhere.
