We're talking about SpaceX specifically, not Tesla or any of his other companies. In the context of SpaceX, what GP said is absolutely true. The rocket industry has not been getting incrementally better over time. If anything, costs have incrementally gone up over time. Until SpaceX, nobody was able to significantly lower launch costs. Then SpaceX came along and succeeded where dozens of previous startups had failed, and the price floor drops out. In this particular case, "revolutionary" is the right descriptor to use.
