Of course there is easily obtainable knowledge, but there is also easily obtainable misinformation. And I don't know a whole lot of people who are seeking knowledge so much as they are spreading misinformation. Let us also not forget what things like auto correct has done to people's ability to spell, as well as speech to text, and simply talking to a phone to ask a question instead of using your skills to type, search, and read. If the internet were being used for gainful knowledge it would certainly be an improvement, but by and large it is not.
