Martin Gardner, writing in 1977. Email was already being sent, telegrams had been around forever. I guess what he describes is more like a fax machine than email?
(The article this is introducing is about ciphers to protect such electronic communications, so this is an introductory sideline.)
@peterrowlett I wonder how common computers with live displays instead of teletype printers were in 1977. I suppose even if people were using personal computers with CRT displays, it would still feel more reasonable to read a letter in paper than on a screen
@christianp@peterrowlett The TRS-80 came out in 1977. I think up to then kit home microcomputers like the Altair 8800 might well have had only a teletype. And only a very niche hobby rather than commonplace.
