I apologize for reading the word "scoff" into your comment about technology, but I think my point that the pervasiveness of social media represents another qualitative (or perhaps "fundamental", to use your terminology) change during that period stands.
This thread started with some one asking whether Tech had played a role in the decline of street gangs.
I am making the case that outside of the smartphone, and faster wireless networks, nothing fundamentally changed between 2008 and now.
So, did the rise in smartphones lead to the decline of street gangs?
