Modern times call for a modern language

The other week my little teenage brother went in a huff with me for some reason, (although it was probably for no reason whatsoever.) In his pit of anger he shouted at me "You're just gay!".
Later that day I watched a film, Good Fellas, in which there is a song. The lyrics include the word 'gay'.
"Pretend you don't see her my heart, although she is coming our way.
Pretend you don't need her my heart, but smile and pretend to be gay."

Now I believe this raises a fairly valid point, you see the language we use is changing right before our very eyes. No more than 50 years a go, the word 'Gay' meant happy, now it's used as a slanderous term for a person who is a homosexual. The same happened for the word 'Queer', which used to mean odd.
But that's not the only example. The word 'Sick' now often means 'Cool', the word 'Mean' means 'Nice', the language is getting turned upside down!

Even the way words are written has been changed, now 'Today' has a 2 in it, and 'Later' has an 8 somewhere.
So where does this end? When sentences are written in binary? Well, I wouldn't be so doubtful, after all, that is a modern language.

This is a very divided subject, the older generations may laugh at people my own age writing things in a short hand combination of letters and numbers, but why? Throughout history people have laboured over the language, continuously moulding it into the perfect form. It wasn't even until the 15th Century we had a J. Look at the Ancient Egyptians before that, who used hieroglyphics to write on walls etc.
I can bet a pound to a penny that people were up in arms when the letter W was added in the 10th Century, although most couldn't read then.
Our language has had to adapt in the past. Latin was scrapped for a more easily used and more durable language which is what we have today. So in this age of Mobile phones and the Internet, the language has again adapted, to be of use within our changing life-styles.

Nowadays, everyone is distracted due to one thing or another. Whether it's work, video games, films, going out, looking after people, cooking, cleaning, driving, teaching, playing...the list is endless. People need a writing style to keep up. How can we progress if we're still on the first sentence, making it completely grammatically correct? It's not even like writing in 'Text Speak' as it's called is not legible. "u cumin out l8r?". Why not even cut out the middle man and use abbreviations for entire sentences? ATM- At the Moment. LOL - Laugh out Loud, and many others.
Even businesses have started putting it into practice, look at modern adverts, and company names. "Phones4U", U Switch, etc.

I personally welcome this change in language. For starters, it's faster, which in today's world counts for everything and it's easier. As for traditional values, well. What is traditional? After all, aren't our values ever changing. Surely if traditional values are not to change, we should be living in caves, like our ancient ancestors?
So, when I get a text message, replacing words for letters, I'll not laugh at the person's lack of grammatical knowledge, after all, it's more innovative than primitive.
But that's just what I think.
