I don't know what makes people think technological progress isn't slowing down. By any metric you choose to look at it is. GDP growth, life expectancy, etc. A modern person would be basically familiar with the household and lifestyle of 1940. A few differences, but most of the technology that we use today was already in place by then. Cars, electricity, washing machines, indoor plumbing, etc. A person from 1940 going back 77 years would be entering a different world. The only real exception is computers, information processing technology. One exception doesn't disprove a trend. And even those have begun to slow down now that we are approaching the physical and economic limits. I strongly recommend The Rise and Fall of American Growth: The U.S. Standard of Living since the Civil War which pounds this point home with example after example of just how much the world changed during the second industrial revolution.
