Some of the predictions are astonishingly accurate. Some are quire funny.
There's a prediction about language:
There will be No C, X or Q in our every-day alphabet. They will be abandoned because unnecessary. Spelling by sound will have been adopted, first by the newspapers. English will be a language of condensed words expressing condensed ideas, and will be more extensively spoken than any other. Russian will rank second.
Of course, it was before two world wars, which introduced corrections into the statistics.
Well done with the "condensed words" and "condensed ideas", and the propagation of English (definitely not a given in 1900).
