Social Media, is it simply old fashioned correspondence?

I recently began a wonderful book " The Guernsey Literary and Potato Peel Pie Society".
It has me musing over the past.

We often hear talk about the onslaught of social media- the texting, the private messages on FB , our status updates, group invites et al, as if this is somehow new and bad. The degneration of human to human contact, the faceless intimacies. " He broke up with me in a text"

The book I am currently reading (  I still can NOT get on the reading books online, bandwagon. I like  to smell  the paper and feel the book in my hands. Books are friends to be revisited over and over, not transiently fleeting across a screen to soon disappear  - but I digress ... :) )

The book I am currently reading has rekindled a nostalgia in me.
It has occurred to me that we have been here before.
I shift my thoughts to calling cards being delivered to its intended by black and white clad butlers with white linens hanging off one arm.
Daily notes back and forth between BFF in stark white envelopes atop silver plates and crisp folds sharing the little details of a life.
 Gentlemen  declaring their undying love to their betrothed with delicately structured prose dancing across parchment.
Appointment cards marking the advances in a day, dance cards filled with potential partners.
A time when we spoke  through the written word more eloquently than we did face to face.

I think on these things and I wonder if we have come a sort of full circle.
Is texting the new calling or appointment card?
Do our status updates compare to those lengthy letters of the trivial details of our daily lives we find so fascinating from jane Austen's world?
Has the telephone been replaced by the written word and if it has, what does that mean for language in the future?
Will it be filled with OMG, LOL ad nauseum in the place 'cordially yours' ?
Will texting become the dance of the prose of intimacy?

I do not profess to understand all this and I can not even begin to imagine what comes next, I simply pose the subject to be pondered and discussed.

 I think I will start paying closer attention to my texts and, iphone spelling allowing, re adopt the ' cordially yours' of yesteryear.

Cordially Yours;
