There's a charming book about a long-distance relationship between telegraph operators called Wired Love by Ella Cheever Thayer. The writing itself isn't anything special, but it is remarkably prescient.
Here's a particularly insightful quotation:
> ... we will soon be able to do everything by electricity; who knows but some genius will invent something for the especial use of lovers? something, for instance, to carry in their pockets, so when they are far away from each other, and pine for a sound of 'that beloved voice,' they will have only to take up this electrical apparatus, put it to their ears, and be happy. Ah! blissful lovers of the future!
The telephone had already been invented at that point, yeah? So the prediction was simply that telephones would become small and wireless. An accurate prediction, of course, but not a shocking one to venture.
Perhaps. Though I would say that we've become very used to things becoming "small and wireless" over the last several decades, so that it almost seems inevitable now, but I'm not sure that's always been the case.
The book The Information by James Gleick introduced me to this bit of history. It's an incredible book for plenty of other reasons, including discussions of West African talking drums, Charles Babbage & Ada Lovelace, and plenty of other things. Highly recommended!
More interesting are the differences caused by the medium of Morse Code. The characters are variable length and the dashes are 3x as long as the dots. So dash-heavy letters* are more likely to be dropped. Also why you rarely see numbers: the longest letter is four symbols but every digit is five symbols. In many cases it would be faster to use roman numerals.
If you look at the attached list of telegraph abbreviations, which is alphabetized by the long form of each word, you will see that U abbreviates "you" (as we would all expect) and Tr abbreviates "there." Are you there?

Note that this was published in 1879!
