I started when I was about 16; so not really that far ahead, only 2 years before this guy did and I'd considering myself pretty knowledgeable in a lot of things and in-fact have often come up with solutions some complex and some simple to problems developers who have been programming longer than me failed to solve in a shorter period of time. Much like anything the longer you've been doing it, the better you get. When you're a programmer it's possible to have been doing it for a long time but fail to stay up-to-date on various techniques and languages that could save time. I've seen many a developer considered to be way above senior struggle to adapt, so I am a firm believer for some people the very fact you've been programming for 20 years longer than someone else is irrelevant in this changing landscape. Give it a couple of years and you'll most likely know things more knowledgeable developers don't know or vice-versa. Just keep at it.
