The official narrative is that over 200 huge buildings were built for the Chicago Worlds Fair only to be torn down a few years later. Everyone believes that story, even though they wouldn't have been able to even complete the foundations of the buildings in time for the fair with 1893 machinery.

This is retarded. You obviously have never been to Paris, cause there are all sorts of original buildings still standing including the Eifel Tower. London, crystal palace, and all sorts of WF buildings remained until torn down years later. Keep in mind that in Chigago, many buildings were temporary and were 'facades' that did not require foundations, so they used wood instead of cement, and other 'faux' treatments.
