Sure. Powered flight went from "not invented yet" to "fastest and safest way to travel" in less than 100 years. Nuclear power has had a couple significant disasters but is otherwise mature. Antibiotics. Rockets and satellites (like GPS). Filmmaking. For the most part, I think major new inventions of the 20th century have taken much less than 100 years to mature. We have science and engineering now, so being able to apply them to new fields is generally feasible. I'd flip it around: what fields still have not matured yet? In what fields, since the dawn of science and modern engineering, is the median project still a failure? I'm hard pressed to think of any outside of software.
