Kudos to you first for recognizing your own error and second for openly admitting it.

I think there many things to consider here. For new developers, I'd encourage you to look for those "old guys" who really know their stuff. There's a lot of unmined gold you can discover there if you find the right ones. I think us older developers would do well to imitate the patience and kindness of Tim Paterson more often. I guess what I'm saying is both sides could do with a huge dose of humility. I know at times I've been the youthful dev out to one-up the "old guys", and I've been the senior dev thinking "these kids today" to myself when dealing with those with a lot less experience. And both of those are bad.

Also, there are many times when a young guy fresh out of college spots a problem, finds a great solution, and makes things ten times better by just doing it! If you're in the business for a long time, it can become too easy to be cynical, and lose your enthusiasm.

I think the best thing we can do is try to let the good stuff from both sides rub off on each other.
