A very famous film begins with the saying ‘the world is changed’. Yes, the World is really changing (we know that it sounds standard but let’s compromise this time), but not in the direction of the era with a lot of challenges and threats like shown in this movie, it is changing towards the digital era with a full of opportunities. Being in real life does not mean full existence today. In real life, people can see and hear you, but if you are not in the digital world, you remain in a shadow.
