A few years ago I had a shamanic vision of "expression-competition." A group of guys stood around in an urban setting, and competed as to who could convey more meanings with, and compact more concepts into, a single sound. A big, rotund fellow wearing a cap stood up, took a very deep breath, and exhaled a single sound that expressed sentences-worth of meaning, and the participants cheered. A strange vision, but not that strange.
It's said the greatest sermon of Shakyamuni Buddha was when he had held a flower, smiled, and didn't say a word. That pretty much said it all. Mantras, incantations, sigils, symbols, spells, etc. are hyper-semantic, hyper-semiotic and yet they interweave with morphic fields.
I'm quite convinced that the proliferation of diagnoses of Attention Deficit Disorder the world over is an aspect of evolutionary, morphogenetic adaptation to increasing historical "velocity" with respect to information exchange. Truncated, abbreviated, encoded information is an essential ingredient of daily parlance. I don't have ADD but I've must admit I've caught myself skipping tweets that are "too long."
This kind of instantaneous processing of much compacted data into shorter and shorter segments of information-conveyance is exactly an aspect of M. Gladwell's idea of "blink," it's exercising a heretofore atrophied dimension of supra-sensory perception. Evolution is proceeding toward the condensation of data into discrete quantum "packets."
For an obvious textual example, ':)' appended to the end of an otherwise potentially misconstrue-able text-message can soften it to avoid misunderstanding. Contextually ':)' would be packed with information, and makes an instantaneous connection on emotional, psychological, and psychic levels with very little cranking of cognitive wheels involved, as a device of information-negentropy. Linguistic-info data-compression is both textual and verbal.
However, the question remains as to if an actual devolutionary dumbing-down is happening, and less information (and hence more noise) is being transmitted by way of compression. Perhaps 'dumbing-down' needs to be defined in context, because in terms of conventional standards hitherto, yes, languages are getting deconstructed. People don't know the difference between 'your' and 'you're' any more since they are now both derivatives of 'ur' (it's probably not putting the cart before the horse to say that texting, instant-messaging, and chatting are more fundamental to language skills today than, say, book- and classroom learning). If a whole new generation learns the written language by way of networking venues, then abbreviations, acronyms, and "special-character" cypher-concatenations will become normative.
In that case, dumbing-down (by current standards, which already are very low, at least in the U.S.), information-transmission efficiency, and telepathic tapping-into sociolinguistic morphic fields will happen all at the same time. Honing the ability, even if unconsciously, of accessing collective repositories of morphic fields is far superior to being dependent on the bulwarks of cumbersome grammar, which can effectively thwart referential opacity.
It seems that logico-grammatical entrenchment of social morphic fields was a provisional Habit to teleologically prepare human beings for a morphic-quantum, evolutionary jump to telepathic, nonlocal communication. It's a move away from Logos to Eros, toward a more inclusive mode of being.
