Did Steve Jobs change the World ? Yes, he did

In April 2003, at the “All Things Digital” executive conference, Steve Jobs expressed that cell phones were going to become important devices for portable information access, and that mobile phones needed to have excellent synchronization software. On June 29, 2007, the first iPhone was released in the United States of America, and this small device with a new concept of mobile phone – which is named Smartphone – revolutionarily changed the world. People become fully communicative not only by voice but by sharing or distributing every sort of data. Conventional cameras disappeared from people’s hands and computer market also sinked.

However, the Smartphone also produced negative effects. Both children and adults spend more time on their smartphones, therefore, face to face dialogues have been rapidly reduced among family members. People no longer call each other when they need to communicate with more than 2 people. Instead, they message each other as a group in order to organize things quickly and more effectively. People continue to spend a lot of time on Smartphones even if they are at particular places such as serious religious sites. Public phone booth completely or largely disappeared from many countries and phone companies switched their business from conventional voice communication to data communication.
