I mean I just read that article and it doesn't seem like a lot will change, sure it can summarize a whole book, or read a larger chunk of code to do thing with, but didn't really see it talk about taking things to "the next level" so to speak.

The researchers are also, excited.

We’re especially motivated by applications that could benefit from longer-sequence models – high-resolution imaging, new modalities of data, language models that can read entire books. Imagine giving a language model an entire book and having it summarize the plot, or conditioning a code generation model on all the code you’ve ever written. The possibilities are wild – and we’re excited.
