What you are getting from HN at your current age with your experience, is not the same that what your young self would have gotten from the same content
I feel the value of HN is greatly reduced once you are more familiar with the industry. But to an outsider this site is gold.
I mean, when you read about interviews and the problems people struggle with you get a sense of what it is. When I read those I thought "That doesn't seem hard, I can do that!", so I did.
I would like to say that I am young and I remember getting turned on to podcasts and reddit and good books when I was 15 or so, and being exposed to rational thought and discussion did a lot for my development I think.
