> What SpaceX did and does for Space Explpration is far beyond what anybody has even dreamed since the 80s I wouldn't quite go that far. When it comes to space, there are lots of very grand dreams (e.g. see https://www.youtube.com/channel/UCZFipeZtQM5CKUjx6grh54g https://www.youtube.com/channel/UCZFipeZtQM5CKUjx6grh54g ), some far from theoretical (e.g. the various studies from the British Interplanetary Society), and some even reaching the prototype stage (nice examples at https://www.youtube.com/channel/UC726J5A0LLFRxQ0SZqr2mYQ/videos https://www.youtube.com/channel/UC726J5A0LLFRxQ0SZqr2mYQ/vid... ). In comparison SpaceX's approach is actually quite conservative (multi-stage, cylindrical, unmanned, liquid fueled rocket). The big difference being that they actually got them flying commercial missions! Plus it turns out that their main advantage (effective reusability) is such a big win that (a) it allowed a startup to leapfrog established military/industrial players and (b) forces everyone to treat reusability as a priority (e.g. adding it to roadmaps, or justifying why they can't). I'm excited to see how their projects like BFR go, but SpaceX's biggest contribution might turn out to be shaking up the industry enough to start trying out ideas which were previously shelved as being too radical.
