Was there more progress from 1890 to 1950 than 1950 to 2010?

Depends.

The technologies created between 1890 and 1950 were more important than the technologies created between 1950 and 2010. I imagine myself living without smartphones, microcomputers and digital cameras, but I don't imagine myself living without water in pipes, electricity, automobiles, refrigerator, cinema, television. The goods produced by the Second Industrial Revolution were more important than the goods produced by the Third Industrial Revolution. OK, i would not writing this post if there were no Third Industrial Revolution, but writing this post is not very important.

But the technologies created between 1890 and 1950 were spread faster between 1950 and 2010. In 1950, very few people in the world had access to sanitation, electricity, television, automobile, refrigerator.
