I'm really worried about this. Not only as far as it impacts computer skills but everything.
I watched a stand-up piece/talk by Stephen Fry and he described how he read the complete works by Oscar Wilde when he was 14. Some books multiple times. I'm afraid that the odds of a 14 year old child will do that have gone down dramatically because of the informational and stimulation overload we are under today. "Smart devices" in particular I believe to be more of a curse than a blessing. I've been trying to limit my use of it and it's been great. Of course it doesn't always work, like right now.
