Just like "quantum teleportation", it's a cool-sounding technique which isn't very useful in the real world. I forget the precise details of his experiment because I skimmed them at the time and realised very quickly that it didn't do what the media said it did; yes, the signal tunnels through in less time than light would take to travel that distance, but it takes so long to start tunnelling that the average velocity is still slower than light.
P.S. I don't believe in FTL or expansionist extraterrestrial sentient life; does that make me "unextropian"?
