Multitasking Do Not Work

In a recent study that was done, it was found that children who are constantly switching between internet phones, Facebook, texting, and the TV are more likely to have social problems. It was also found that heavy multitaskers experience cognitive issues, such as difficulty focusing and remembering things. These people were actually worse at juggling various activities, a skill crucial to many people's work lives, than those who spent less time multitasking. It turns out that people need face to face interactions with other people and internet phone conversation do not count. These interactions teach children the social skills that they will need in interviews and then the working world. Then again, we live in a world that is very digital and many of the tasks that we do involve the internet somehow. There does have to be a line somewhere because the human element is something that cannot be replaced. What are your thoughts on this issue? Is it the multitasking that we need to blame or something else?
