That being said, I think AI could be great at assisting generation of complex interactions and storylines and behavior with the human storyteller focusing on the artistical part of the narrative.
Much like those years the instruction set will get amended, the hardware will have an AI coprocessor and eventually, as technology progresses, we will have everything integrated in same CPU (or APU if you prefer this term). My 2 cents
This is why I put some emphasis on having AI assist the artist writing the stories in a similar fashion how modern professional translation works: AI translate texts and the human focuses on the consistency, coherence, tone and expressing the nuances.
A perfect (popular example of that): Harry Potter. There's just too much nuance in the names of everything in HP, from the creatures to the characters to the houses. Translating HP requires a heavy dose of creativity and sensibility that you can't leave up to an AI, it's a work of art. Harry Potter translations are often used very frequently in universities as textbook examples on the _art_ of translation.
In the same way I cannot see the sensibility and artistry of creative humans being replaceable by computers, I can only envision AI as tools to often provide and assist and generate quantity with the artist providing the actual "soul" to the stories and dialogues.
