I came across this document http://www.hedweb.com/manworld.htm#faq containing a plain english explanation of the Everett interpretation. While it is clear that the author is very much in favor of this interpretation and has objections to others, is there any thing here that is fundamentally incorrect or out of date (not his philosophical positions, but his facts)? Particularly this statement: prediction occurs when a theory suggests new phenomena. Many-worlds makes at least three predictions, two of them unique: about linearity, (See "Is linearity exact?"), quantum gravity (See "Why quantum gravity?") and reversible quantum computers (See "Could we detect other Everett-worlds?").
