Information is information. Everything can be described in binary terms.
Binary digit is how actual brain scientists understand bit, because that’s what it means.
But “brains aren’t binary” is also flawed. At any given point, a neuron is either firing or not firing. That’s based on a buildup of potentials based on the input of other neurons, but it ultimately either fires or it doesn’t, and that “fire/don’t fire” dichotomy is critical to a bunch of processes. Information may be encoded other ways, eg fire rate, but if you dive down to the core levels, the threshold of whether a neuron hits the action potential is what defines the activity of the brain.

If it’s not re-defining the term then I’m using it like the paper is defining it.
Because just understanding words to respond to them, ignoring all the sub-processes that are also part of “thought” and directly impact both your internal narration and your actual behavior, takes more than 10 bits of information to manage. (And yeah I do understand that each word isn’t actually equally likely as I used to provide a number in my rough version, but they also require your brain to handle far more additional context than just the information theory “information” of the word itself.)
