Funny. I was just speaking to someone the other day about this.
Many people like to say that as technology expands, humans lose "human interaction". That we, as a society, become more disassociated. I feel like this is untrue.
In my experience, technology has increased human interaction. Prior to texting, there were family members that I rarely spoke to. Reaching them through a phone call or in person was difficult but I found that they would rapidly and frequently reply to text messages. Now, we have much more communication AND it seems to create a stronger connection when we do see each other in person. It eliminates that awkward, "we really don't know each other well so what in the world do we talk about" feeling.
It allows you, via social networking, to connect with old friends and rebuild relationships. It aids you in finding completely new friends. I have made many real and fun friendship via Livejournal. I've also begun meeting new local people in my area via Google+. And by following my gym's Facebook page am developing new friendships with the people who attend the Zumba classes I go to - so they become more than just a face in the class.
There's also a wealth of information available via the internet and the speed of communication is fantastic.
Sure, there are negative impacts. All good things must come in moderation and I think the internet/texting/social media is highly addictive for young people. I think that it's not outrageous to consider teaching young people to not rely on technology too much and to be wary of it. Please, no teen suicides because of an idiotic post on Facebook. Also, texting while driving. But moderation also needs to be taught in regards to food so it's not a completely unique problem.
