What three things do you think will become obsolete in the next ten years, and why?
I think Facebook will become less a place where people go all day every day and more an archive of old photos and a "remember that" thing. People will have one, but from the past, like they do with MySpace now.
Desktop computers will be few and far between as everyone moves more to mobile. Sort of like the wired connections are. So it will all be wireless and portable, tablets and phones and small laptops.
In 10 years I think the term "skinny jeans" will be used to refer to the past only. They aren't flattering on enough people to stay long term.
