A lot of people are bashing the author and the article saying that the tone is condescending, kids do know how to use computers etc. I think his point is that kids do know the "what" part (browsing,texting,fb etc). The question is: do they know or care about the "why" and "how" part ? Should they care ? Should they not care ?
There's no inherent reason for them to care and it's incredibly insulting to presuppose that an entire generation should care about the same things he does - especially when these types of people purposely make it more difficult for people to care (example: being sarcastic, condescending, and "calling the President")
