Here's where the other side gets it wrong from the start: this isn't about whether kids are smart enough to use a phone. Of course they are. It's about whether a device engineered to capture attention belongs in hands still learning impulse control. A smartphone isn't a neutral tool; it's a slot machine with a camera and a doorway to strangers. The cost of waiting until 13 is mild inconvenience. The cost of getting it wrong is sleep loss, cyberbullying, and habits that harden early. If a kid needs to call home, give them a basic phone. The other side calls restriction unrealistic; I call it a boundary.

Picture a ten-year-old stuck on homework, needing to look up volcano facts. A shared tablet or school laptop handles that fine. So my opponent's research point is fair, but it doesn't prove a personal smartphone is necessary. A basic phone for calls, plus filtered school devices, covers safety and learning without handing a kid an attention slot machine. And recording video? A family tablet does that too. The other side keeps describing what a phone can do; I'm asking what it does to a kid who can't yet regulate it. Waiting until 13 is a boundary, not a punishment.

We can agree on something real: learning and safety matter, and phones can support both. But my opponent's own list shows the problem, games, distraction, forgotten homework. That's not a side issue, it's the whole issue. A device built to hook attention in a kid still learning self-control is a bad trade. If a school task needs research or review, a shared tablet or filtered laptop does it better. If a parent needs contact, a basic phone works. The other side is describing useful features. I'm asking about the user. Wait until 13.
