On the technical side, I completely agree with this article. Most people my age (late 20's) and especially younger ones, don't have a clue about the insides of their devices, or how the internet actually works. They also don't seem to be interested in a lot of this stuff. They also tend to think that everything that has to do with their devices is complex.
On the 'functional' (for lack of a better word) side however, they seem to know exactly what to do on the internet. They know how to get attention on the internet, what their peers are interested in and how to get as many likes as possible. They live on the internet, live stream everything they do and make lots of selfies. This seems to be the reason why we're starting to see lots of younger kids becoming YouTube famous, or starting viral marketing companies.
The last thing, to me, is the part where people really become 'digital natives' in stead of 'technical natives'. Also, because most devices are so hard to open, most kids won't even get to see the technical side anymore, unless they want to build a gaming PC.
