If you put any stock in the fortunes, IMO that's in the same ranks as crystals and witchcraft. Maybe it's not necessarily a belief in God, but it's epistemologically the same.
My god, the no fun police. Fortune cookies are just a fun little thing people have entertaining thought experiments on what the statement in the cookie could be related to in their lives. There is a very near 0 number of people who take these seriously.
Fortune cookies are the same kind of woo that carnival fortune tellers are, or astrology horoscopes... or religious dogma.
They can be useful to help someone answer their own questions and come to terms with difficult situations. Tarot works that way. But there's no power outside the cards or fortune other than how they change your head.
