Can't you see the trend emerging today? Entrepreneurship is "cool" and every year seems to be ever more encouraged. At the same time, the internet is leveling everything. Barriers to entry are being plowed across the board. For example look at Arduino, a lot of the things people are making with it aren't exactly amazing. But consider how many posts you've seen of people with 0 experience in electronics, doing things that previously would have been "advanced".

That trend is only going to continue. Think about scaling a new website today, I can go from idea to scalable infrastructure without ever leaving my chair or breaking the bank. Imagine how 3D printing, and other new technologies are going to enable a new generation of people to do cool things.

None of this stuff is out of the grasp of teenagers either. I would not be surprised if you start seeing more and more stories about teenagers building new things, and making a few bucks while they're at it. They've always had the creativity, and drive. But now they have the capability.

Look at youtube, i've been watching videos made by teenagers that look better then most movies made in the 1980's. SLR's, and super high quality video, plus cheap computers & applications are enabling amateurs to do near professional quality stuff.
