Imagine that you were live around 2010. You went everywhere with your Nokia phone in your pocket. Only when it's ringing, you took it out and answered the call. Meanwhile something are changing, but you didn't know. Such as Iphone would replace Nokia to be the first place brand. Then around 2013, everyone was excited to buy smart phone instead of their old phone which felt like a brick in their mind. Later, we were thankful for the services of the soical medias which helped us reduce the cost of calling and texting. Every place was covered with WIfi. It's very cheap for internet. It seemed like that everything would go well until we find that everyone put their head down on their phone wherever and whenever today. It's a big problem which we didn't think of 14 year ago. Parents put their children's phones in some secret places where their children can't find during summer vacation. Adults are tired of doing anything after staying up later to watch videos on their phones last night. Keep our phone away from us is the hardest thing to do. I am afraid of thinking of what the world will be around 2030. What's wrong with the world?
