As somebody who is fairly tech-savvy, I am surrounded by people who will take a stand against technology at a moment’s notice. This is especially true when technology seems to be successfully replacing more conventional methods — some even environmentally harmful, such as paper.
When the issue of using technology comes up, though, I would myself strongly back a minimum age requirement. I never had my phone until I was 17 or so. I think that 15-16 years is a good limit, not because of elitist adult thinking, but mostly because the Internet, to the unaware, can quickly become one of those forbidden dark alleys no ten-year-old is sent into at night. Or worse.
