That reminds me of a joke.

A museum guide is talking to a group about the dinosaur fossils on exhibit.
"This one," he says, "Is 6 million and 2 years old."
"Wow," says a patron, "How do you know the age so accurately?"
"Well," says the guide, "It was 6 million years old when I started here 2 years ago."

From Wikipedia: this is only a 1-sigma result compared to theory using lattice calculations. It would have been 5.1-sigma if the calculation method had not been improved.
Many calculations in the standard model are mathematically intractable with current methods, so improving approximate solutions is not trivial and not surprising that we've found improvements.

Oh certainly, that series took quite a risk on writing style and it's quite divisive.
If you enjoy fantasy, you could try her other series as an alternative. The Inheritance Trilogy is a more standard writing style.

I almost put The Fifth Season down after the first chapter, I remember thinking: "This author has a chip on their shoulder". I'm glad I persevered though, and I definitely recommend the series to people as it is quite different. I'd suggest giving it another shot.

Claude 2 would have a much better chance at this because of the longer context window.
Though there are plenty of alternate/theorised/critiqued endings for Game of Thrones online, so current chatbots should have a better shot at doing a good job vs other writers who haven't finished their series in over a decade.

As a counterpoint to other comments here, I didn't like Babylon 5. I gave up in the first season on the episode about religions, where each alien race shows a single religion but then humanity shows an enormous number of them.

Showing planets in sci fi as homogenous is a common trope, but such a simplistic take. This resonated poorly with me as I felt the aliens all behaved exactly like humans as well, to the point where you have stand-ins for Jehovah's witnesses. That episode cemented for me the feeling I had when watching. Babylon 5 is racist against aliens.
