Thanks for this excellent article. Just a day after reading it I came across an article in Wired (https://www.wired.com/story/karl-friston-free-energy-principle-artificial-intelligence/) about the "free energy principle" - https://www.fil.ion.ucl.ac.uk/~karl/The%20free-energy%20principle%20-%20a%20rough%20guide%20to%20the%20brain.pdf - which corresponds quite nearly with the predictive processing model. This insight into the workings of the brain (and not just the human one) may become incredibly impactful soon, especially in the world of artificial intelligence
