why are we still using telephone numbers? Why not use names, instead of numbers, to connect to people.

I’ve wondered why telephone numbers don’t have check digits. It would reduce the incidence of wrong numbers by 90%. Yes, it would make them longer. That mattered more back when they might only have been 5-6 digits. Now that they are commonly 7-8 digits or longer (particularly for mobile phone users), it seems less of an issue. Come to think of it, why are we still using telephone numbers? They’re an idea that dates from the 19th century. Why don’t we use 20th century Internet-based technologies, such as the Domain Name System? Use names, instead of numbers, to connect to people.
