1. The necessity of adapting to the lure of technology in order to successfully navigate the modern world.
2. The incalculable benefit such devices can provide if used correctly.
It's really not a difficult skill to master. When a child is emotionally and intellectually ready for unfettered cell phone/internet access, mastering how to make a post on Facebook (email-text-blog-instagram-hackernews-whatever) will not be a difficult skill to master.
"2. The incalculable benefit such devices can provide if used correctly."
Do you have the same opinion of television?
There really were people who thought television would be chiefly used as a way to educate the masses. Television is just a medium like any other, mostly crap, with the occasional sublime or brilliant show.
Same thing with your cell phone. Most of the content you access will be crap, occasionally finding something awesome or beautiful or brilliant.
I'm a Dad, so I fully support Louis C.K.'s opinion that parents should filter the content and devices children access in a way that's age appropriate. Most adults have a hard time putting down their device and interacting with their environment. Teaching our kids this skill early in life is to their long term benefit.
No one is suggesting such a thing.
The ability to maintain effective and skillful communication in a world of constant distraction will be essential in the coming decades. "Protecting" a child from such a smartphone will produce an adult ill equipped to cope with the advances of the future.
No.
The ability to avoid constant distraction will be one of the most critical skills. The ability to focus, to think through a problem, to write a substantial essay, to plan, to evaluate your goals, values and priorities in life. These skills will be critical to flourishing in the coming decades (as they have always been).
