Everytime you use a technology, there is a risk associated with it. There are dangers everywhere in life today. The only way to be safe from dangers of modern technology would be to go back to the stone age. Cars are awesome!, but we should stop using them cuz a lot of people die due to car accidents every year. Why do we still use them? i wonder. It has not even been proven that WiFi is bad for health and people are already afraid of 'em. I don't think anybody is afraid when they turn the key in their cars. Maybe BBC should show a program on road accidents instead of something soo less dangerous.
