Clever title

Uncalled for riff on the synopsis:

The conundrum of forgetting comes seems to come down to a gradient of persistence, whereby new stimulus prevails over memories.

If it didn't, the organism sensorium would be a captive to memories, which once noted seems like an obviously maladaptive dynamic.

Resolved: Perfect memory would preclude your sensory awareness...

So the next question is why does the gradient of persistence have such a shape / slope?

The dynamic of knowing vs. perceiving looks like some tradeoff over persistence and speed of access (a la caching).

Are memories something like deferred stimuli?

Thought must be some other domain within this gradient, subject to other dynamics?

What structures of the blob of protoplasm which is the brain manifest as Euclidian geometry, phonetic language / alphabet, and Turing machines? How does something so mushy give rise to such rigidity... which in turn bizarrely can model mushiness. Almost like an error condition.

Stimulating, guess will have to read the paper!
