Generation 4: Bloat the software with so many unnecessary features, the users must want to chat with each other no?

There isn't any generation 4. The functionality of the software is ubiquitous by that point. Nobody cares anymore except when they absolutely have no other choice. By that point even if you generated a brand new implementation you would struggle to give it away unless it was just one small part of a new innovation.

Mustn't forget that social media sharing to show that we are also hip and down with the fellow kids.
