The internet has changed things quite a bit in not only the fact that people can see what people do. It's also changed what people consider to be important and it's changed what young musicians think is important as far as playing goes.
I think it's funny that young folks will tell older guys that things have changed and they can't understand the new ways but when older guys will notice a change they've seen the young guys want to deny that change.
"No ... we were always that way .... you just didn't see it".

The world has changed a lot and you can't simply acknowledge the changes that you
want to acknowledge.
Music has changed in a lot of ways.
One thing is that everyone now has access to tens of thousands of tunes. When I started you might have 2 dozen albums and listen to them over and over and over for a year. That alone dramatically changes the relationship to that music. You're going to inevitably know inside and out anything you've listened to a thousand times. A lot of current music listening is relatively superficial.
I'm not saying one is better than the other ..... I'm just saying they're definitely different.
And that's probably one of the lesser changes.
