It goes both ways. Imagine what motor vehicles and transportation in general would look like today if we were able to manufacture and process titanium alloys like we do steel. How far away are we from that breakthrough?

Conversely, what would the world look like today without steel? No airplanes? No WWI nor WWII? No huge panamax ships? No global markets?
