As an offshoot of that effort, one thread emerged which is relevant to this language sub-forum.
The main work that led to this are not fully cooked and so these offshoot ideas are not fully cooked. But I figured why not cook this interesting offshoot in public!! It is non technical and general in nature. So let your imagination and creativity flow. It is a lot of fun.. Comments, supporting and opposing points are most welcome!!
The outlandish question is: Is written communication necessary? And what is its future? Will there be a time in the next century when it will be so minimized that it is used only for special cases ( like tagging the recordings ), and venerated as vestiges of an once useful mechanism...( one child: anDa kalaththilE pesaradayellAm ezhuduvALAm!! another child: ezhudaradunnA enna? )
Remember, I did say 'outlandish'...
The main idea is that the written language is a lossy communication mechanism. Several important aspects of the meaning involved in communication are lost once you write it down: The pauses, articulation, the intonation, the emotion, the body language etc. We try to capture those with commas, periods, question marks and exclamation marks but as we know that does not do full justice. It took the internet age to even come up with emoticons. A written sentence is a discontinuous and chunky representation of the continuous sentence of verbal communication.
Now, written language was invented to satisfy certain needs. Written language helps with communication among people who are separated over space and time. This is called space and time shifting. ( modern examples: Mailed letter helps with both space and time shifting. Instant messaging and SMS help with space shifting. )
Another obvious need that it fulfills is, it helps with storage and archival of communications and expressed ideas, in the form of manuscripts and books.
Consider these three things: Space shifting, time shifting and storage.
We now have technology for all these three things. Phone calls ( audio and video ) bridge both space and time. Recordings of phone conversations and voice mails provide one method of storage. Audio books, read by the author, turns the written text into emotion rich audio.
Consider 3D video and audio communication which can accomplish all the above three in a much richer and natural fashion.
But there are several magnificent advantages to written text. This posting itself is an example. I can develop this over time, edit it, wordsmith it etc. before sharing. That is hard to do with speech currently. But is that because we are so used to written communication, we are blind to richer possibilities? May be there can be tools that are easy to use which helps us do the same thing with voice or even 3D video and voice. Also, we are all used to reading text much faster than listening. May be over time, our brains have evolved to specialize in such things. Also, we can skim through and get the gist of it.. But these are all artifacts about improving on written communication. If all our communication is 3D video and/or audio, there will be enough tools and methods developed to achieve the same things, we just do not know yet. At least, that is the rebuttal by the proponents of this futuristic possibility, in terms of this think tank'ish exploration.
So the outlandish questions to explore are:
-- With the advances in communication technologies and gadgets, now and in the future, are we seeing the end of written communication? Not immediately, but over the next 50 to 100 years with the decline starting soon or having already started.
-- Not because people are lazy but because of the deficiencies with the written form..
-- That is, is this a case of our ancient ancestors inventing a mechanism which is inferior in nature but a necessary evil which is being replaced by a much richer method which has become only possible due to technological achievements (Assume dirt cheap internet bandwidth and storage costs... it is the future we are talking about )
-- If Humans do not write at all, what are the implications and consequences? (e.g. Education system will focus on speaking, listening and arithmetic instead of reading , writing and arithmetic. That switch does not seem to be bad at all..)
-- As a special case, currently this forum is written language based. How will a full fidelity 3D audio/video version of this forum look like? Is it for the better?
-- Remember, those who do not like that all full fidelity, can always notch way down and step back to written communication

If you are game to thinking like this, and if you have read this far, remember this is not about language but only about script based written language. So authors and poets need not worry!!
Also, as we all know people bemoan the fact that people are losing writing skills because they write so little. This is not about that bemoaning but the opposite. This is about restoring full fidelity to personal communications.
There is an obvious parallel in music. With music we will never equate the communication capabilities of an actual piece of music to its notation. For communicating music over space we use streaming, for communicating music over time, we use recordings/upload/download, for storage we archive the recordings. So in a way, written communication if ever replaced by full fidelity 3D audio and video communication has its precedent in music. If this parallel holds, the transcribed form of the communication ( i.e. the written text ) is just treated as a low fidelity notation and relegated to that status, as an educational tool to learn to speak and as a reference.
Our vedic ancestors believed only in oral transmission. But the problem they had and worked very hard to fix was, it is not easy to detect distortions over generations. But with current recording technologies, that is no longer a problem.
