Is generation Y addicted to use of technology in their everyday life?

Yes, definitely. I have a dog and it is very frustrating that it’s hard to walk down the street without a risk of someone bumping into her because they are staring at their screens as they walk. Probably at least a third to half of people walking on the street are using their phone in some way, and on buses it’s nearer to 80%. Only one or two of them will be talking on them, most will be checking it in some way. Even if they don’t have signal, ie on the underground, they play solitaire if nothing else. My younger brother, growing up in the 90s, used to have no other entertainment than his Nintendo. He never read a book for pleasure and didn’t like to watch TV with the family. Maybe it is just his character but my nephew is now the same - I have been in the same house with him often but literally have not seen him for years as he doesn’t come out of the room because he’s playing on his computer. His mum brings food into him and he only goes to the toilet when he is absolutely desperate. His mum says he has no problem in talking to people online, he likes to play multiplayer games like Call of Duty and has a headset that he uses to speak to people on in the context of the game. My niece, who is his sister, sometimes messages me but when I see her in real life she says almost nothing.
