I think it's interesting to think about, and it gives form to a loose collection of observations I've had myself. Thanks for posting Vasilisa, I'll be reflecting on things through this lens. (The shortcomings of language, in particular, English has really intrigued me for quite some time... I studied Japanese and there are concepts inherent in their words and writing that convey deeper meaning. As is also the case with what I know of Maya hieroglyphs. I've often mourned what I think of as the single-dimensionality of English. Though, I've had other competing thoughts around that but won't go into them.)
It's seems we are awash with the refrains of history. We all have access to so much historical information now, that there are many timelines and experiences to absorb. Our present is inundated. I'm reminded of the idea of the value of learning from history, but it's interesting to think about the possible effects of historical events living long past when they might have, were they not preserved so well for future generations. (Hmm, thinking...)
I think it's a reach though to ascribe the use of things such as facebook to the preservation of self for posterity or a means to ward off death. It may be on that continuum, in that I think of it as a way to ward off a feeling of irrelevancy, and a way to satisfy urges for attention. Or socializing. Not bad things, just not as lofty.
I think our avatar/internet selves can take on a life of their own that is quite seductive though and may be preferable to real life existence for many at some future time.
