In my earlier reply to GP, I had forgotten about space exploration, and I think that is a major technological advancement that would amaze someone from 1922. However, I still think that someone from 1922 would expect such things of 2022 in a way that someone from 1822 would not expect of 1922. 1822 - 1922 is the difference between being a barely-technological world to being a fully-blown one, in many, many fields.
