Someone from the Roman Empire would have had a good understanding of the world in 1750. Ocean travel better, some advances in building large buildings, otherwise not that different.
In 1900? Quite a bit has changed.
The general shape of daily life today is not so different than say 1970. Email instead of letters, cell phones instead of searching for dimes for the pay phone.
But we fly in jets that average about 450 MPH, cars with a top road speed around 60 or 70 MPH, television but now with an Internet or cable feed, supermarkets are much the same, etc etc.
