Well, if you look at all these technologies, they didn't revolutionize when they were created, they took a long time and revolutionized when they matured. Radio exists prior to the 30s but it was experimental and niche, same with networking and computers. I think that the space decade is going to be this one. The last one, the revolutionary things that took hold were social media and cryptocurrency. Social media is shaping up to be a big disappointment, at least in it's current iteration.
