It's a good observation, but IMO this has been the lifecycle of many, many technologies. Take the jet engine. It was invented in the 30s, applied to exotic military applications in the 40s and 50s, available as transportation for the rich in the 60s and 70s, and finally became the dominant long distance transport mode for everyone by the 80s and 90s.
