Stanley Bing proposes some killer apps. An excerpt:
In the future, it is possible that if you can't express a thought in a single character, it's not going to get heard. The letter "h" will be accepted as the universal symbol for the word "hi," for example, just as "k" has come to replace "Yes, I'd love to have dinner with you -- I've been missing you and looking forward to spending some time with you after several weeks of really hard work where we've had no time to be together." Other letters of the alphabet will be quickly assigned similar duties, and if you don't like the idea, I've got a letter for you that can't be printed in this magazine.
