To a good degree, I agree with the entry there. We no longer live anywhere near the natural way we were supposed to, and this includes communication. Will this present day behavioral and communication revolution be seen as 100% positive 100, or 200 years from now? I doubt that by then, some unseen costs that we're already paying, will not be accurately noticed and measured. Be it more anti-social behavior, obesity, eyesight problems, or general lack of fitness, something will stand out as a significant unintended effect. Perhaps the end will more than justify these costs, that mitigating solutions will be found and promoted, but I cannot help but feel a bit sad knowing that some of the old values are vanishing, all fall into disuse.
An email will never be quite as precious, as personal, as the old-fashioned handwritten letter, and to think of courtship done over IM, especially when you could see one another, is really quite sad.
