Well this is trivially true, but it really doesn't mean anything. If copyright length was 500 years this would still be a true statement.

It's ridiculous that there are 100 years old works of art created by people who have been dead for three quarters of a century which are still under copyright. You cannot spin this as a positive thing, I'm sorry.

Works published two years after the end of World War I will enter public domain in 2047 (Agatha Christie's first book). Star Wars will enter public domain in the 2070s. It's mad.
