Is this long term really a problem though? Regression to the mean: No one cares about the specific slang of the 60s anymore. And the hip slang of today will be out of fashion in 15 years.
In a similar vain the extreme T9 keyboard text message abbreviations of the youth in the 2000s did go out of fashion because of automatic spell checking and speech recognition of modern smartphones.
How long term? What's "a problem"? We know with certainty that given the passage of enough time, the speech of "these kids today" will be completely unintelligible to you.
Definitely. Things are clearer when you write formally and strictly adhere to grammatical rules. When I'm speaking casually I omit words and (ab)use punctuation much differently, and while that is perfectly acceptable to do, it is more complex and ambiguous to parse.
As far as I'm aware the same pattern exists in a lot of languages and dialects, and it's possible to define formal AAVE too.
>I don't think there is anything "formal" about Standard English.
"Standard" English as she is spoke? No. But a3n was specifically talking about the formal version often called "Standard written English". It is very prescriptive and less flexible, which makes it easier to parse.
> Can you give an example of what you're talking about? Which grammatical rules do you have in mind?
Let's start with "every rule involving punctuation".
Another ambiguity is parse ambiguities like " I saw the girl with the telescope." What does "formal" English say about that?
Absolutely. It follows a strict set of formal rules and you can readily find sources to learn those rules. Heck, copyeditors regularly debate the specific nuances of how to consistently write Standard English.
Other dialects (and spoken language) are far less formalized. Where is the AP Stylebook or Strunk & White for AAVE?
