How do you know? You would have to take surveys of people alive from 1899 to 1949 (taking the surveys in 1949) and compare that to surveys of people alive from 1949 until now. First time I used the internet, it was amazing, but I don't gasp in amazement every single time I log on today. If someone asked me if the internet changed my life, I'd say probably, but it's a routine thing now and I'm accustomed to it. If you asked people about cars or planes or radios in 1949, they'd probably say about the same thing. It's hard to define what constitutes a real change in daily life because people become accustomed to things so quickly. In 50 years when I can cook up a new pair of shoes in my assembler for 25 cents, I probably won't think much of it because it will be the fifth time I've used it that day.
