If one was born in 1971, when Intel released the 4004 microprocessor, it is likely to be pure luck if one has seen a computer at 13.
If one was born in 1983, the year in which the Mototola DynaTAC 8000X was first sold, it will be pure luck or privilege if at 13 years old one had a GSM phone.
If one was born in 1991, chances are that at 13 one had access to the Internet. It’s not a given though.
If you were born in 2007, the year the iPhone was introduced, you are 13 years old now and have never lived without a super fast network connection from your mobile computer.
