In 1900 the Ladies Home Journal magazine predicted that by the year 2000 the letters c, x, and q would be banished from the English alphabet.The expectation was that spelling would be phonetic and that those letters would be unnecessary. It was a perfectly logical prediction, but no more correct than the predictions that the use of jetpacks, teleportation, videophones, and smell-o-vision would be widespread. (Note: I make no predictions in this dictionary.) See also Smell-O-Vision, teleportation, and videophone.
