I think this is more of a version of the "why have we stopped making good music/movies, almost everything today is garbage?" issue. With the benefit of hindsight, we only remember the greats (and the very worst villains) from past eras. While if we look around today, we see all the people who will never make it into the history books, just like we see all the songs and movies that will never become "classics."
Edit: And yes, the internet has brought about immense and immeasurable benefits to science and innovation. It can both be true that most people on Facebook are dunces and getting dumber because of Facebook, and that there has been massive developments in research and development that would not have happened without the internet.
