Look, I'm studying undergraduate philosophy with no intention other than why not. Would I say I could learn the material on my own w/o college? Absolutely but I like the organized structure of college w/ professors, peers, etc. Am I getting into debt? A fair bit. Is it worth the trade off? I certainly think so. Will I say that five years from now? Most likely. Because here's the thing: education as a means to an end…
Spoiler. Been there, done that. Unless you're at an Ivy, if you're majoring in philosophy, you'll not think it was worth it in five years. My sin was Classics, but similar outcome.
Assuming you're on HN because you're teaching yourself programming, the sting will be somewhat lessened (that's the route I took), since you'll at least be able to get a job.
But it'll still sting to make those massive loan payments knowing that nothing you learned is helping you with your professional life, and that things like philosophy, mathematics, and languages (and computer science!) can be learned just as easily with discipline, YouTube, and a few good textbooks.
It's very easy to delay the pain of loan payments when you're in school, but they'll be there waiting for you, inevitably, through sickness and health, marriage and divorce.
If you have endless curiosity, college is even less worth it. Instead, being loan-free gives you the freedom to work in areas that truly intrigue you, and to work in very low-paying internships while you're learning.
But I know I won't convince you. Likely no one could have convinced me at the time (although only one person tried, once).
Edit: if this were the 1970s or earlier, when you could pay for college classes from waiting tables or a $10,000 loan (inflation adjusted!), I'd absolutely say go for it. But taking out even $50,000 in debt at age 18 for anything less than a guaranteed job with a good income (physician assistant, nursing, accounting) is mortgaging your future. Taking out $200,000, which is the going rate for most [edit: should read "many, private", and is probably closer to $100,000] liberal arts 4-year-degrees, is insanity, but between culture BS about degrees and "academic counselors", I know it may not seem that way to you right now.
