While there are a bunch of reasons to counter your view, ill just use one. You can learn now, in 5 minutes, more than you could learn 15 years ago, in a day. And thats if you were in a good country with libraries and supported knowledge. A 3rd world country child, would NEVER dream of learning ANYTHING 15 years ago. but now they give out internet in public spaces n shitty laptops. and they can surf away into knowledge. You can learn so fast, so easy, so much now, if you went back in time you would feel despaired. Just imagine for a second 20 years ago, that you couldnt google a particular subject that came to your mind. You couldnt ask a question, then boot up a browser and find the answer immediatly. And as for veritable source material, while the internet material isnt as trustworthy as librarian and encyclopedic support, you have SO many more different sources of information, the sheer ammount more than makes up for the less trustworthy sources.(personally i always found encyclopedic knowledge extremely bias, even with all the scrutinized checking).
Oh and, if you think that no one uses the internet for knowledge....
thats just the lazy people. And lazy people have never seeked knowledge, no matter what era it is.
