I have a step-brother who is very young right now.
He knows, very well, the ins and outs of a cell phone, can find videos, play music, and so on. This is barely at the age of 4 or 5.
This guy assumes kids aren't getting access to technology or media, because it's hidden away on cell phones a kid can't access.
Except they can. Not only that, they have the internet, and the fact that people listen to music everywhere now, radio, television, culture. They see the text on phones, and they likely will want to learn to read it as well.
There is no danger here, just luddites.
