Mathgeekjoe - No. The question can get taken a fair number of directions, but I have no interest in limiting my sons exposure to much of anything. I wouldn't let him pickup a charged capacitor without telling him (happened to me), or... I don't know, experiment with lasers without proper supervision, but no. I will not limit him.
Nah it was directed at Mathgeekjoe for his quote "Because if you live to 100, half you life is after the age of 50, before the halfway point of 100 years you are too immature to use a smartphone."
Hey, can't I make a joke?
