The smartphone itself is something no one had a hundred years ago. Love it or hate it it can do so many things undreamed of back then and it has become almost universal. Yes there are drawbacks to it but judicious use of it can be a boon. One can even read FR with it....something else that didn’t exist 100 years ago.
I've heard it said that the typical smartphone of today has more computing capability than was found on board Apollo 11.
