Back in the days when there was no Internet and anyone who had a PC used it mainly as a word processor or a calculator or to play (very primitive) games, Stephen King wrote a short story (I believe, if memory serves, that it was published in
Yankee magazine) called something like "Word Processor of the Gods" (or something else
). In it he creates a machine that basically does what the keys you punch tells it to do. Example: type the name of a person you hate, then press 'delete' and that person ceases to exist in your life. Type out a scenario you would like to see come true, hit 'enter' and the scenario materializes.
