There are unquestionably positives and negatives to the increase in technology in the life of today's young adults and teens. Here a just a few:
access to ideas and information that they might not have access to in their daily life, this includes access to other religions and cultures
ease of communication with other, friends, family, etc
unique and new opportunities for learning that simply don't exist without the technology
the growing need for instant gratification in all areas of life
a gullibility for technological media- as said above "if it is on the internet it must be true"
the ability to express views and ideas without having to face the consequenes, this is a problem for adults too, but I have seen an enormous amount of what equals cyberbullying with my middle school students, they say things about themselves and others that they would never say in person for fear of what might happen
internet predators and over exposure to sexualization
Now there are many more examples in the positives and negatives, these are just off the top of my head.
As for solutions to the negatives, the answer is in good parenting and education. Right from the get go, from the time young children are using computers and Ipads and other technology they need to be taught parameters.
NEVER text in the car. Have a healthy dose of skepticism about everything you read on the net until you can find ways to back it up. If you wouldn't say it in person, don't put in print. Everything you put up on the internet can never be taken back. Don't trust people on the net, if you don't know them in real life, you really don't know them. And technology is a wonderful and useful luxury, but still a luxury, learn to live without it.
Children need to have these basics (and others) taught to them early and reinforced throughout their childhood and teens. Like any behaviors it is up to adults to teach children, not expect them to know things. If these issues are never addressed then the problems continue and grow. This is just one more responsibility that parents and teachers have in today's world.
