I agree with you. You should read the Orwell essay I linked.
I saved it to my Kindle. I rather liked his Homage to Catalonia.
However, language is more than an organic growth; it is an instrument of communication.
There's no dichotomy here; language is an instrument of communication subject to organic growth.
Could it be that the English language has ceased to develop and begun to fossilize in this day and age? Great standardization has occurred as a result of technological progress.
As long as slang and subcultures exist, both of which are present
almost of necessity with every language (because humans are inventive), fossilization of a language will be impossible short of language death (See Classical Latin, Classical Chinese, etc). The kind of standardization that you're here referring to is the result of
fiat on the part of the academy with regard to what constitutes a written and verbal standard and, surprise surprise, the literati and well-to-do decided their own was "correct". Even it isn't stable, and again, who gets to decide the standard? English doesn't have a regulatory body like, say, French or Hebrew, and why would it?
It was decided that the
correct pronunciation of British English ought to be based upon the accent and dialect of English spoken amongst the upper-classes of southeastern England, Japanese is supposedly standardized around the accent and dialect of Japanese spoken amongst the upper-classes of Tokyo, and so on. There's nothing intrinsically better about these dialects, and neither are they necessarily more deserving of being the basis of standardization, but the class-oriented power-plays that established these "standards" were quite real and often arbitrary.
The notion that English has ceased to develop is, to be frank, funny, as technological progress has arguably sped up the rate of language change. Sure, one might call the slang found online just plain incorrect- but slang eventually becomes dialects, and languages, as once said, are just dialects with an army. My great-grandmother, then one-hundred and two, complained about how difficult it was to understand people under the age of twenty, and this was a woman who grew up in urban, middle-class Cincinnati in its heyday- not neck-deep in a holler with a car that needs warsh'd.
French, Italian, Portuguese, etc were all once lower-class Vulgar Latin which the literati mocked as not being
proper Latin. Sanskrit continued to be the literary standard (by what standard?) and what constituted
proper speech for thousands of years while its vulgar varieties split and became modern Hindi, Bengali, Punjabi, etc. My point in giving all of these examples is to demonstrate that language change happens and is inevitable, and that's alright.
