Like many of these types of inquiry, the details matter. For example: cold fusion is real. It's just not terribly useful for powering a city. But you can use it as a neutron source for generating the short half-life radiological treatments for cancer [1]. For this drive, what we have is an experiment that begs a theory. There's something interesting going on, and so far it eludes easy explanations. Quite possibly we'll get an innovation out of it in experimental setup, or best case real, easily verifiable thrust is detected. Chances are there won't be any new physics, but rather a very clever engineering exploit of what was already known (but not properly applied). Enjoy the failures in science; it means we're actually trimming the dead ends carefully instead of assuming all innovation is low hanging fruit. There's a lot of bunk out there, but there's also tons of neat edge cases to map out! [1] A friend's husband works in one of those labs. I forget the mechanism at play (I think it was cavitation), but it was room temperature fusion generating neutrons. It'd never be self sustaining for power, but still incredibly useful.
