Troglodyte Implications

I just printed a conversation in GMail and it worked very well. Just what I wanted and nothing more. But, as the pages were printing, I started thinking, what's the point of printing anything? In the very near future, all communications will connect to everybody, on-line. Printing will be instant garbage. Why would anybody do it? So that somebody could read it? Why would they do that? Are they not connected? Who are these people? Meanwhile, I needed to print the damn thing, and so I did, despite the troglodyte implications.
