I think technological progress has slowed down dramatically. in 60 years we went from the first plane to landing on the moon. We haven't been back to the moon since. The invention of electricity, atomic theory, radio, the internal combustion engine were all far more world changing inventions than anything we've developed over the last 60 years, including the Internet. For instance, we are desperately trying to keep Iran from getting hold of 60 year old technology (uranium refining)!

I love studying the period in history between the franco-prussian war and World War II (1871-1940). The speed at which technology snuck up on the world and completely changed it was astonishing.
