#32If you find water analogies helpful for circuit elements, here is one for the memristor:
"The closest analogy I can think of is a sand filter, an item of apparatus used in water-purification plants. As contaminated water flows through a bed of sand and gravel, sediment gradually clogs the pores of the filter and thereby increases resistance. Reversing the flow flushes out the sediment and reduces resistance." -- https://www.americanscientist.org/article/the-memristor

#33"Acts like a neuron" is BS. Neurons are more like individual computers themselves, with all sorts of activity at the subcellular level.
Interesting, where can I read more?

Abstract
Current hardware approaches to biomimetic or neuromorphic artificial intelligence rely on elaborate transistor circuits to simulate biological functions. However, these can instead be more faithfully emulated by higher-order circuit elements that naturally express neuromorphic nonlinear dynamics1,2,3,4. Generating neuromorphic action potentials in a circuit element theoretically requires a minimum of third-order complexity (for example, three dynamical electrophysical processes)5, but there have been few examples of second-order neuromorphic elements, and no previous demonstration of any isolated third-order element6,7,8. Using both experiments and modelling, here we show how multiple electrophysical processes—including Mott transition dynamics—form a nanoscale third-order circuit element. We demonstrate simple transistorless networks of third-order elements that perform Boolean operations and find analogue solutions to a computationally hard graph-partitioning problem. This work paves a way towards very compact and densely functional neuromorphic computing primitives, and energy-efficient validation of neuroscientific models.

#36Acts like an artificial neuron model, not a biological neuron.

#37This is really interesting work, but I feel like the way the article summarizes it is getting it wrong. First Single Device To Act Like a Neuron One thing that’s kept engineers from copying the brain’s power efficiency and quirky computational skill is the lack of an electronic device that can, all on its own, act like a neuron. It would take a special kind of device to do that, one whose behavior is more complex tha…
This has nothing to do with "modern neural networks". When they say "neuron" they mean an actual biological neuron. The main application for this device type is brain simulations.

Didn't HP want to build a new type of computer on it?

Hasn't this been debunked: https://www.quantamagazine.org/neural-dendrites-reveal-their...
