Bottom line: there is no "new technology" that can make a rocket significantly faster or cheaper to operate. The earth's gravity/friction well and the limits of chemical/atomic forces are the limiting factors. To space cultists, this rocket is a symbol to be used as a way to justify further fanaticism towards sci-fi fantasies that are themselves motivated by un-resolved emotional needs and fears and the average existential angst that has always fueled belief systems, paradise fantasies, and the standard escapes from mortality and impotence. A rocket in no way shrinks even the shortest trips in our solar system to human exploration scales. Self-landing propulsion stages don't change any of the factors that limit human exploration of even the closest rocks in our own little planetary neighborhood. Ego and existential angst are fueling the hysteria that is continued interest in Musk's childish endeavors. Did Richie Rich do science?
