No, history has nothing to do with it. This descent - and its basic errors - has been discussed to death over the last ten years.
As has also been discussed, the ascent was mostly changed for the better. There’s a shock. Change was good.
Again... all opinion based on individual thoughts about what is good and what isn't. Even the idea that you perceive things to be "basic errors" is a matter of opinion. Look Martin, you can feel whatever way you want to and I almost never react to it until you make some snide comment implying my inability to judge things based on my own feelings and desires. Then I get angry and perhaps say some things that are less then wonderful.
I fully respect your grasp of the history of everything Disney, I do not always agree with your "let's never change anything that I liked" attitude that you use against a different view point. Most of the time it is not your knowledge of what has happened before or what is happening now, it's that interpretation based on how you think things need to be. Although it is OK to think differently, it is not OK to make condescending statements when someone disagrees with your opinion.
I am one of the first ones to agree that the original EPCOT was wonderful, but, I am also one to admit the it is obvious that the idea was more ambitious then it was possible to maintain. You don't need to be a rocket scientist to know that the world has changed and they could no longer depend on private enterprise to continuously upgrade, at their expense, current technology when so many other avenues became available to market things then there was in 1982. Those days are gone and the margin of return on Disney footing that expense that in affect would be benefiting the sources of that change more then Disney itself were easy to see, once the technological explosion happened.
That was after EPCOT was built. Before then no one realized the speed with which technology was going to re-invent itself. On top of that it became a reality that the general public didn't want to be riding in slow moving rides filling them full of knowledge they didn't ask for. Yes, many of us wanted and encouraged that, but, declined attendance at EPCOT made it obvious that intellectually this was a great thing... as an entertainment venture.. not so much.
I have no desire to continue this discussion because I'd be surprised if anything new would come to the surface at this point. We will have to agree to disagree and stop trying to imply stubbornness on either side.
