And if every generation of teens wants to grow faster, experience everything in life from early ages, follow the weirdest trends, what will things be after a few yeas?
How will the teens of the future look like? Let's say after a 100 years.
Technology
This will surely be one of the most significant changes. Technology is constantly evolving and with great speed. Ten years ago I was really proud of my 512 MB card for my Nokia smart phone. It was amazing - you could take pictures, listen to .ogg, record videos, had cool coloured games and programs (I think they weren't apps back then).
It's logical technology will change and it will evolve because of the young people. They are the main consumers.
So if now people love to take selfies with their multicored, 41 MP, 5 inch super-smart phones, imagine what people will be using in the future. The idea of a smartphone is to have every technology you can use in one device. So right now you have a camera, tablet, music player, recorder in one. Maybe in time they'll put even more stuff.
