In spite of all the faux defense of EPCOT about following Walt's wish, please... EPCOT Ctr. was not what Walt's dream was. In fact I doubt that the concept ever even crossed his mind. It was much more of a tribute to him then a completion of a dream. I'm sad that Walt died so young, as it was a huge loss of an incredibly creative mind, but no one should confuse the dream with EPCOT Ctr.
As someone said, logically EPCOT Ctr. really did show how unrealistic his dream was. It could have been built but it would never have had the desired result. When he was starting to think about stuff like that computers were closer to being punch card based then the massive explosion of Technology that really had just started when EPCOT Ctr. came into existence. That coupled with the great City of Celebration failure more then made it clear the existing physical alteration every time something new happened was not doable without massive long term corporate support. Just like the sponsorship of the EPCOT pavilions it would all hinge on the economy and just how willing corporations were willing to give away their new technology after the creation of the internet.
EPCOT Ctr. was a great park with exciting new things and for a while it was a wonderful place to visit, but, it was not able to keep up with ever expanding technology and over a decade lost is shine and therefore its pull to others that already were individually more advanced than EPCOT could keep up with. So it started dying on the vine. In order to maintain it started to have to be party central appealing to more basic things like food, drink and flowers.
I also miss the original, I was one of the people that went there every trip, but, even for me a lot was just like watching reruns on TV. You can handle a few but, before long they have lost all their sparkle. I'm sorry to see it go, in Future World, but in reality going to Future World in recent years was more like a history lesson then a new technology exhibit. I'm hopeful that the new EPCOT will bring people back that aren't there just for the alcohol and are excited about that area. I also feel that not a lot has changed in World Showcase that isn't an addition to a benign park that was and is special, but needed a shock therapy to restart the heart beat. Those dreaded IP's are going to add to what is there and if it ends up to be a puberty and beyond MK, then I welcome it. There was a time when horse and buggy transportation was in great demand, nothing lasts forever.
