It is hard to say, and this arises for many reasons. the biggest reason writing is so up in the air is because of the vast amounts of knowledge that can be transferred so quickly form one soul to another through writing and the subsequent. When a population is being controlled, then an art form such as writing can be very dangerous. This is a reason that reading and writing have been so downplayed and labeled as "dorky". It is establishment propaganda against the thinkers of the population.
With that in mind, we can expect writing to become more lucrative if a way of exploiting it successfully comes about. Otherwise it may be pushed and forced underground, so as not to educate the masses too much. Writing isn't like the music and movie industries. Writings cannot be so easily manipulated, and thus are not pushed as much by the corporations. They would rather writing seem like a detrimental path.
