I'm 35, and I think the younger generations are extremely lucky. You have every single little bit of information at your finger tips.
Google, and Youtube are amazing sources of information.
You can learn for free, if you know what to look for and how to learn.
A quick example, my fiancee came home one day with a 300 level maths uni assignment, which had some complex calculus equation solving rubbish in it. I recognised the notation from when I was at uni, but I couldn't remember how to do it. Even then, when I did do it at uni (15 years ago) I futzed my way through it because I didn't quite understand it then even....and the tutor and lecturer for 300 maths I had were useless.
Anyway, I looked it up on Youtube and someone had actually put up a video explaining exactly how, why, and what to do. He did multiple examples on the video showing his working and thought process the entire time. After 5mins of that, I remembered how to do it, but more than that, I understood it more than I did back when I was actually at uni.
Everything is available now. It's amazing.
The guitar stuff, my God. Be happy that you will NEVER know the pain of hearing a guitar part, looking to find a tab book in the store, seeing the tab, and going, "HUH?!"
...AND THEN, going back to the guitar store to try and find an instructional book that explained how to do what you had just seen, finding the book, reading he explaination and trying to play the exercises and going, "HUH?!?"
Now, Youtube, search, find, watch someone's hand close up, and slow, then fast, click on description and find tab. lol. It's just all there now, on demand.
My fiancee is of a younger generation, and there I can see many differences. The main one being, she doesn't care about the HOW of the way things work. Me, I always go out of my way to find out how things work...to the point of disassembly, and reassembly. She just cares that whatever is meant to come out, comes out at the end.
But in the end, there are gems in every generation.
