Same here, though they say this in the paper, about the experimental confirmation they propose: "...To be clear, this would not be some simple analogue or proxy representation of a space warp phenomenon, rather it would be a genuine implementation of the idea in physical fact with observable consequences in the laboratory – just not in the dramatic form of a craft bound for a distant stellar destination."

It seems that they're proposing a real, achievable-with-current-manufacturing-skill experimental contraption that they think will be able to create a real, not analogous, not hypothetical, honest to god warp bubble. So I'm waiting for a real physicist to wake up, come and crush my dreams on this one.
