I don't think you could teach someone to be a genius, but you can certainly teach them to not make rookie mistakes and to look at writing the way a writer looks at writing, and not just the way a reader looks at writing. There are a lot of techniques and skills that can be taught that will be helpful to anybody, no matter how gifted they are, and I think writing programs can be very good for people.
