I dont get the downvote. I had no internet access until being an adult. What I had was a pass for the public library, which I made use of from age 14. I had a membership card for the cities outdoor swimming pool in the summer – big kids party, there was table tennis. I was a member of the chess club, the IB, the Judo club, and the Scouts. I had two best friends (whom I knew from the Scouts); we would regularly visit each other, and through them, I knew many other children. I didn't need the internet at all until I was 25. Banning the internet for all children in a country until the age of 16 – treating it like a movie for adults – would likely be a blessing for their real-life social connections, at least it would probably not at all harm them.
A young child using a Linux, just having a restricted amount of knowledge resources will probably learn it better than with the internet connected. At least I made that experience. I learned programming the Web with just having local access to the SELFHTML documentation.
