A great story may end with “The End,” but its characters do not necessarily stop living in our imagination. Generative AI may now be able to continue those stories in ways that feel surprisingly natural.
Last weekend, one of Hayao Miyazaki’s animated films was shown on television.
I have seen it many times before, but Nausicaä is still charming no matter how often I watch it, and the story never loses its excitement.
But what happens after the words “The End” appear?
In human society, people never simply “live happily ever after” forever. Perhaps one day the heroine marries someone, gives birth to an adorable pair of twins—a boy and a girl—and before long a struggle over succession breaks out.
Or, of course, something completely different might happen.
As long as the original creator is still active and able to continue the work, the sequel should probably be written by that creator. Unfortunately, for many reasons, that eventually becomes impossible.
American television dramas and movies often continue through sequel after sequel, and perhaps that is only natural.
Life does not conveniently stop just because the words “The End” appear on the screen. In a sense, the characters in a story continue to live lives of their own.
And generative AI is becoming capable of telling what happens next while maintaining a surprising degree of consistency with the original world.
Take The Tale of the Bamboo Cutter, for example.
I gave AI the following prompt:
“Could you write a roughly 400-character synopsis for a short story set twenty years after Princess Kaguya returned to the Moon? The main characters are Princess Kaguya and her twenty-year-old son, a prince. His father is one of the five noblemen who once proposed to her. Kaguya returns to this country with the Moon’s highly advanced science and technology, and the prince meets his father. He later marries an Earthly princess, remains on Earth, rules the country, and brings happiness to its people. The story should end with ‘and they lived happily ever after.’”
The AI replied:
“Twenty years had passed since Princess Kaguya returned to the Moon. The Emperor and the old bamboo cutter had already died, and the story of the Moon Princess was slowly fading into legend when a silver vessel descended on the outskirts of the capital.
From it emerged Princess Kaguya, unchanged by age, together with a young man of twenty. He was her son, born of one of the five noblemen who had once sought her hand in marriage. Before returning to the Moon, Kaguya had told no one that she was carrying his child.
Having studied advanced medicine, agriculture, and energy technology on the Moon, the young man returned with his mother to visit his father. Now an old man, his father saw something of the young Kaguya in the prince’s face and immediately understood.
The prince eventually shared the Moon’s knowledge generously with the people, reducing famine and disease and bringing prosperity to the country. He then married the daughter of an Earthly king.
Princess Kaguya returned once more to the Moon, but the prince remained on Earth. As a king linking two worlds—his father and mother, Earth and Moon—he ruled wisely, and the people lived happily ever after.
And so the story ended happily.”
It sounds almost like something Shinichi Hoshi might have written, but it is remarkably well constructed.
Personally, the only things that felt slightly out of place were the silver spacecraft and the fact that Princess Kaguya had not aged at all.
I also found it interesting that the AI deliberately avoided revealing which of the five noblemen was the prince’s father.
After only a few rounds of discussion with the AI, I suspect we could produce a genuinely moving Princess Kaguya, Part Two in just an hour or two.
Ordinary writers may have a hard time competing with this.
These days, people often talk about the importance of having practical, hands-on skills.
The number of white-collar jobs will probably decrease dramatically.
Even doctors may eventually do little more than perform examinations according to AI recommendations, while some kinds of work are largely handed over to AI and humans simply supervise the process.
The question will then become what we do with all the time that AI gives back to us, and how we use human creativity.
But how many people will still be willing to go through the troublesome process of creating something themselves?
I do not know how close we really are to the so-called technological singularity.
But there is little doubt that we have already entered an age in which AI can perform, one after another, tasks we once believed required uniquely human creativity.
Perhaps human beings are now being forced to reconsider, and rapidly change, the very way we live.
“The End” may soon mean only the end of the original story—not the end of what can be imagined next.
