Sadly, I think a lot of this is a generational thing. When I was first learning how to do sound the Internet didn't exist. You had to go to the library, find anything you could on the subject that was even remotely related, and read every word until you finally figured out what it all meant. That at least got you in the ballpark. Then you dragged out all the gear, hooked it up, and figured out how to make it work.
When I first got a real sound company job, I actually went through the file cabinet and read every single manual on every single piece of gear they had. I was just overjoyed to be able to find all of the information in one place. Of course that also quickly made me the resident expert on every piece of gear in the shop, since I knew every arcane application, connector, and function of every piece of gear we had. That in turn went a long way to my rapid career advancement. Yes boys and girls, knowledge IS power.
At the risk of sounding like a grumpy old man, now information is just a simple Google search away. There just isn't the same motivation to absorb large quantities of knowledge in the offhand chance you might need it sometime in the future. Instead you know that if you need to find the information, you can just Google it and there it is. While I love the access to information that the Internet provides, I'm not sure it's all a good thing.
