One thing I think is interesting about the paper is how complex systems (like the brain) change over _time_ rather than at fixed points, and if those changes are computable in any meaningful way. Like if we created an AI 100 years ago, could the AI 100 years later learn how to use an ipad or understand what twitter is or what a meme is? What if brain changes from cultural (environmental) change are both complex and thus creating mathematical models that would change the intelligence of the AI in the way the brain changes is impossible. Like physical changes in the circuits in the brain that are so distributed, interconnected and complicated and subtle yet very specifically "tailored" to the complex system so as to make them virtually impossible to abstract or model in any way, and thus changes the "mathematical model" of the brain that is sort of "virtualized" at a fixed point in time. Edit: Well to put it a little more explicitly: What if the real reason brains are intelligent is not because of the brain alone, but also because of the underlying physical systems like molecules, maybe even going all the way down to quantum mechanics and that those lower levels cause changes over time that fundamentally alters the function of the brain but still has the evolutionary potential of the lower level physical stuff. If you have 2 levels: 1) the brain 2) the underlying physical stuff below neurons 1 is a virtualized fixed point in time that we can model and 2 is part of a complex system that alters 1 but importantly in a way that cannot be computed without simulating that stuff at the lower level. I feel like this is sort of implied in the article because either intelligence can be abstracted completely accurately or there will (as the paper claims) always be lower level physical changes that alters the intelligence in a way that cannot be computed at the brain/intelligence level. I don't know if this is true though tbh
