The original story is The Hare & The Tortoise
A Hare was making fun of the Tortoise one day for being so slow."Do you ever get anywhere?" he asked with a mocking laugh."Yes," replied the Tortoise, "and I get there sooner than you think. I'll run you a race and prove it."The Hare was much amused at the idea of running a race with the Tortoise, but for the fun of the thing he agreed. So the Fox, who had consented to act as judge, marked the distance and started the runners off.The Hare was soon far out of sight, and to make the Tortoise feel very deeply how ridiculous it was for him to try a race with a Hare, he lay down beside the course to take a nap until the Tortoise should catch up.The Tortoise meanwhile kept going slowly but steadily, and, after a time, passed the place where the Hare was sleeping. But the Hare slept on very peacefully; and when at last he did wake up, the Tortoise was near the goal. The Hare now ran his swiftest, but he could not overtake the Tortoise in time.
I do agree that deconstructing the structure of narrative and using generator like tracery can help us produce new versions of story.
But for me, the innovative or creative part of the story still relies on the writer or human beings to write. Machine can give us more random and different possible results, but we still need to provide and create the original elements to generate by ourselves. I think this part is the most difficult part.
And also, for tracery, it only allows us to generate story based on a certain structure. We can use it to pair different style, and point of view maybe, but it's hard to change ordering, duration, focalization.
