Lots of warranted energy around recursion in AI rn!
But what we really need to crack is the capacity for an AI to interrogate and reflect on their own world model. This is the big, beautiful kind of recursion that keeps the organism globally coherent [and curious] over time
If we crack that, I bet it scales, because you can use your own outputs (mind) as the data to reflect on ad infinitum, as well as never ending hunger for epistemic foraging...
because now you know what you do not know.
A certain baseline intelligence is needed but then it’s takeoff—this is probably what the cognitive revolution was, a turning inward that allowed us to “grasp” facets of our mind and keep them stable long enough to share them with others...
Which in turn birthed our ability to 'know' our own knowledge: epistemic agency
What you need is basically recursive self-interpretability
—a beautiful loop.
A core function of cortex is predicting what happens next given the world's state.
This great recent paper from Oxford shows how cortical layers may use a clever delay trick to learn to predict.
A simple illustration can explain the main idea.
Here is my toy model and notes:

1/2) Have you have noticed that the forward process in a diffusion model looks a lot like the reparameterization trick in VAEs?
It turns out that there is a deep connection!

Amazing paper. All the good stuff: brain dynamics, state trajectories, embedding, links to arousal, tracking full dynamic state with a single measurement.

Dopamine (DA) in the dorsolat. striatum (DLS) is a teaching signal that shapes learning.
DA in DLS ≠ RPE but = to stimulus-choice associations relevant to a learning strategy.
This can be beautifully explained as saddles in a loss landscape.
Here is my toy model and notes:
The brain's hardware evolves to make sense of events that happen in space and time. The Lateral Prefrontal Cortex has expanded that hardware in primates. Check Alex and Megan's work if you have not done so, and find what NAS are
