Interestingly, there was a class of people who never missed that from day one. "Don't believe everything you read on the internet," our teachers warned us. We scoffed: if we could be so stupid. No one believes anything you read on the internet.
Only looking back do I notice the slow change. We have become a people who believe everything they see on the internet.
Speak for yourself. I only believe things I see on the Internet if they fit my preconceived ideas.
These days, if something is NOT on the internet, it is suspect. Even if the evidence is in a well-researched book, if people can't find a URL for it, they immediately dismiss arguments out of hand. You see it all the time on this forum as well.
After speaking with the professor that teaches the class, his instinct was also to check that the internet says it's right before updating the lab manual. I had a simple argument based on a well-known formula, but ultimately it's the internet that decides whether it's right or not.
And the "traditional" media scrambled, falling all over themselves, desperately trying to become relevant as their business model disappeared, moving their content online, competing in the cacophonic nightmare of screaming known as the internet. Little did they know that adding more signal to the noise just tricked us into believe that noise was signal.
