Last year's news, but still has to sink in. Read it, but beware exaggerations like "electronics had no rigorous mathematical foundation", which would set quite a few physicists and engineers spinning in their graves.
What Leon Chua rightly noted, and described, was a missing fourth passive electrical (not electronic) two-terminal component. The difference is that electronic is usually associated with so-called active devices. Those have three or more terminals (e.g. vacuum valves or semiconductor transistors), and the third terminal controls the electron flow between the others.
Given enough active devices, you can mock up practically anything. For example, with capacitors and transistors (and a power supply), you can make an imitation inductor - with a limited range, but good enough for an integrated circuit when the real thing was hard to build.
The great novelty with memristors is finding a real physical basis to provide the desired behavior in a simple, manufacturable two-terminal device.
P.S. The A.I./neural-network angle seems to originate with the device's creator (Stan Williams). With all due respect, I doubt that it will have all that much impact from that side.
