I was just at the Biennale di Venezia [1]. It, like Art Basel, was well attended.
These art-oriented fairs may have supplanted science and technology. (It coïncides with the 1970s and 80s’ anti-intellectualism in America.) On the other hand, science and technology discussion is far more realistic today, at the average dinner table, than it was in the 1950s.

The last world's fair held in the US was the 1984 Louisiana World Exhibition. https://en.m.wikipedia.org/wiki/1984_Louisiana_World_Exposit...
