> The physical infrastructure projects enumerated above occurred before 1970 to a disproportionate degree. Why? Probably because the author either can't count or doesn't know what disproportionate means. 1/3 of the entries on the list going back to 1889 happened after 1970 (which is about 1/3 of the timespan). That sounds very proportionate. Why no questions about the long gap after the Eiffel Tower? The most disproportionate things about the list are World War II and the fact that the list is extremely arbitrary.
