I don’t understand. Can someone please dumb it down one setting on the dial? What makes this obviously superbiologically capable?

The obvious things are size, speed and integration with existing computers.
A neuron is measured in micrometers, a memristor in nanometers (and the paper suggests even single-atom devices may be possible).
A neuron can fire at most a couple hundred times per second; a memristor has "subnanosecond switching speed", i.e. it operates in the usual GHz operating frequency range of modern computers.
And you can integrate them at the circuit level, so they can draw on the superbiological capabilities of existing computers at native speed.

Downsides:
* routing is a BITCH
* cooling is a BITCH
* noise is a slightly nicer BITCH
* we are very early in building real stuff with this
But yeah, it's cool, I hope it works out (otherwise I chose a deadend/false start for my PhD :-)
"We conclude by noting that biology has always served and will continue to serve as a great inspiration to develop methods for achieving lower-power and real-time learning systems. However, just as birds in nature may have inspired modern aeronautics technology, we eventually moved in new directions and capabilities for faster travel, larger carrying capacities and entirely different fuelling requirements. Similarly, in computing, modern application needs to go beyond those faced in nature, such as searching large databases, efficiently scheduling resources or solving highly coupled sets of differential equations. Interestingly, some of the observed characteristics in memristors may similarly provide ‘beyond biology’ opportunities in computing, taking advantage of the novel device dynamical behaviour and the network topology inspired by biology. In this regard, concepts such as the memory processing unit represent truly exciting opportunities down the road. To achieve these and other new computing systems of the future will require persistent and creative research that goes beyond any single discipline, and must include insights from neuroscience, physics, chemistry, computer science, and electrical and computer engineering, among others."
