OK, I've finally finished reading the Nature paper. To me the interesting, yet bothersome, thing about this design is that in contrast to the past fifty years of trends in electronics, it actually has moving parts. We're not just sloshing electrons around the place, we're actually moving dopant atoms through an amorphous solid, by applying ridiculously enormous electric fields. My worry is whether this will wind up being durable, or whether the response is going to change after these atoms have been yanked back and forth a few billion times. The paper certainly doesn't say anything about extensively testing these systems.
