I was 15 of 16 aswell when I got my first phone.
An LG, didn't even had wifi.
And today you see 6 year olds playing with the phone of their parents. And 9 year olds who have their owner phone.
But when I was young In wasn't allowed to spend all day on the PC. 1h a day (max 2).
When I got older it didn't mather that much anymore, but maybe all of this is a little bit the fault of the parents?
And I believe that in the future the smartphone could be gone.
Just like the normal mobile phone is old right now.
In that time who thought the mobile phone would be replaced?
good question. I know the time where kids were were allowed to spend 1h a day on the pc and things have definitely changed
