Wow, it’s a tricky question! I’ve never imagined what our world would be like if the internet collapsed one day. All of us know that without the internet service, we literally cannot do anything. I mean, when we go out, we would be carrying more than one mobile phone, you would need a wallet in case you buy something. You might have to write letters to your friends or clients and send them to the post office first. You cannot register the online courses you are interested in, instead, you need to go to school everyday. And many other terrible consequences. That’s a disaster.
