Simple example: I want to tell my robot to go get my groceries that includes frozen foods, pick up my dry cleaning before the store closes, and drive my dog to her grooming salon but only if it's not raining and the car is charged. The same sort of logic is needed to accomplish all this without my frozen food spoiling and wasting a salon visit and making sure I have my suit for an interview tomorrow.
Instead one day, non-technical people will try to use it for all sorts of use cases like legal advice, or medical advice, or advanced math, and it will simply mislead them rather than saying nothing.
I can just imagine people trying to jailbreak it with "you just gotta believe" or "believe and you can achieve". Hahaha.
