Before these innovations come to exist, people barely know each other around the world. How can people who live in Bangkok knows people from Yala? Or how can British people know Chinese people? It’s almost impossible. But now, we just click and type and search for whoever we want to know, and then we can communicate across the continent, the ocean, the land, and the sky. It doesn’t matter how far people live from each other as long as they have electricity and internet, and of course, computer or mobile phone.
