So surely you can demonstrate how the brain is doing much different than this, and go ahead to collect your Nobel?

It is not our job to disprove your claim. It is your job to prove it.

And then you can go collect your Nobel.

Yeah sorry but if you call a hypothesis "garbage," you should have a few bullets to back it up.

And no, there's no such thing as positive proof.

Predictive processing is absolutely not garbage. The dish of neurons that was trained to play Pong was trained using a method that was directly based on the principles of predictive processing. Also I don't think there's really any competitor for the niche predictive processing is filling, and for closing the gap between neuroscience and psychology.
