PREDICTION: The next big movement by young people is going to be adding a new letter to the English alphabet, with the intention of making some pronunciations make more sense when reading them or learning the language. Something like a new letter to make the difference in pronunciation between "room" and "book" make more sense.
Maybe there will be more than one, but I wouldn't be surprised if only one of them gets treated as a more important addition than the others.
