EPCOT today is year round food festivals.
I would say it's now a year round festival that includes celebrating food, cultures, and the Earth.
The Disney board, execs, and imagineers decided to recreate the World's Fairs that birthed It's a Small World, Carousel of Progress, et. al. And they did it by holding a pillow over E.P.C.O.T.'s face.
People like World Fairs, right?
The World Showcase part of EPCOT is pretty much the same, but Future World hit a snag: The corporations which sponsored (paid big bucks to build the pavilions) weren't keen on spending millions updating pavilions. And so as much as some still loved the original rides... they were becoming outdated or past their prime. And no sponsor money to update them. So things... languished. With attempts here and there to update stuff... with big gaps of nothing new in between.
Communicore's displays of advanced tech quickly became laughably outdated... if you ever had a chance to experience it. How were thousands of people supposed to experience a dozen tech stations?
Future World died from the reality that high-tech corporations weren't going to bankroll new attractions every 10 years.
So, when people say that something doesn't fit EPCOT... they're mostly saying it doesn't fit Future World. And they're right. It doesn't fit Future World, which is why it no longer exists.
The better question is does it fit a World's Fair. Does it fit a festival center?
