I was very introverted throught my childhood and spent my first school years' recesses not talking to anyone, just mindlessly wandering the hallways and yard. It got to a point where I didn't even know many of my classmate's names, even after spending years "with them".

When I grew old enough to have my own phone that I could bring to school, it made recesses more bearable. It didn't sabotage or disincentivize any social interactions, because before that moment I had almost none with peers. Looking back on it, I didn't "lose out" on socialization because of phone use, as I simply didn't have any beforehand.
