The thing that occurred to me as I was reading this is how different life can be depending on how much energy is cheaply/freely available.
Think back to within the last century: I have more horsepower sitting in my driveway than the average small village of 100 years ago (and that's not counting the actual horses in my pasture :-) . Kilowatts of cheap electricity are available at every wall socket. How has that changed our lives? How much different would life be if gigawatts of power were available at that same wall outlet at the same cost?
"The same day as an article on the subject" is probably a little premature for any theories about its utility, too, although I'll certainly be interested if anyone who knows what he or she is talking about with physics thinks that this could be used to build an ansible or something...
you could argue that limitations for ftl come from translational symmetry (conservation of momentum and energy), but that's not what was broken here, as far as i know.
