People will always look for ways to make things easier. probably everything you do in real life and every tool you use will somehow become internet related.
Also things will probably become more universal, get a pc, get the internet, do a course and your buisness can go international, oh and maybe learn another language. Things will probably also move more server side, universal domains that can store your documents, online office apps.
I hope unemployment doesnt rise, there might be more people sitting at home.but people will just have to learn different skills. you can have an interactive teacher in hard to reach places. What the internet is doing is taking the world and making it smaller.
as for traffic decrease, lets hope for the best. but after they have finished milking us for petrol they will come after us with electricity hikes (oh wait thats happening now). Anyway all that traffic will become virtual.
Real shops will always exist, I think humans will always need to interact, its just the interface that will change.
As for faster internet connections,we will need them, the queus will definately get shorter and move faster in real shops but hopefully it wont move to the net where I get a message on my screen that says im number 5 in the queue, please be patient and there is some music playing through my headphones
and a virtual magazine filled with adds, maybe if it lets me select a track it wont be so bad.
