We need to be careful of how technology controls us, for sure. Especially with young children.
Is SMS speak itself a problem? No. This kind of shorthand has been around since morse code, possibly longer. Language evolves, and the way we speak is different to how we write formally, and that's different again to how we text.
With the modern smartphone having quick text capabilities with a full QWERTY keyboard and the quick swipe method, the older ways of texting with the drawbacks for having to press the keys several times for a single letter, there's less need for the text-speak anyway.
I think if we view any of the technological "advances" in isolation and carefully parse them, it's easy to make a case that they are wonderful: A smart phone is a lifesaver when you are lost in the wilderness or your car breaks down in the middle of nowhere. Who could argue with that? No one. Ergo, smart phones are wonderful.
It's when you look at the technological "advances" as a whole that you start to see a different picture. The addictive nature. The reprogramming of brains, whereby people can think and communicate only in eight-word bursts. The destruction of social relationships, whereby 4,000 anonymous "friends" and "followers" substitute for real family and real friends. The ability to surround oneself 24 hours a day with people and information sources that think exactly like you do and reinforce all of your delusions and prejudices. And on and on.
If I could make these "advances" disappear overnight, I would cheerfully accept the risks of being lost in the wilderness or my car breaking down in the middle of nowhere, just as I did 50 years ago. But those who are in the grip of addictions and delusions - in this case, about 85% of the world - are seldom able to see the reality of what is happening to them.
I recently paid for my stepdaughter in Russia to spend two weeks with us in Arizona. Although she is 37, almost her entire visit was consumed with checking her smart phone and posing for photos to post on Facebook. I'm not sure she even realized she had actually visited Arizona. It was bizarre. It was like "documenting for people I don't even know that I have been in Arizona" was vastly more important than "enjoying my visit to Arizona."
It's tangential to this thread, but another example that occurred to me is the state of "music." Yes, every generation thinks the next generation's music is demonic. But I stayed current from the earliest days of rock 'n roll through the New Wave and Punk. I loved Buddy Holly but likewise Blondie, the Sex Pistols, the Clash and Nirvana. I was well-known as a veritable Rock Historian. When rap and its successors came along, however, it was as though someone had slammed a door in my face. "It's not that this is bad music," I thought, "It's simply not music. It's like a jackhammer assault on your brain. It revels in it's stupidity and obscenity. This is surely what music sounds like in Hell." Some 25 years later, i think the same thing. I am surrounded by neighbors who are enamored of this filth. I don't know what is going on inside their heads that they actually choose to purchase and listen to it incessantly, but I am convinced it's one more example of the supernatural evil that pervades our age.
