I see what you are talking about.

The twitter culture. The tendency to consume fast and short information (and usually meaningless) in order to satisfy our need to "gain" some current knowledge.

I don't know if this aspect could end up creating a new Great Depression , but it can certainly create a new generation of people, that while having the opportunity to learn important knowledge, end up deciding to consume stupid content, worthless content. A person living like this would have a hard time raising the new generation.
