First, allow me to preface my comment by saying that I am in no way an expert in Disney history. You guys likely know a ton more stuff about the CofP than I do, so I could totally be off-base here, but...
I've seen many people on this particular thread talk about how they are bugged by the last scene in CofP because it is so "out-dated."
Wasn't this ride created for the World Fair in, like, the 1960's? Isn't the last scene supposed to be what the Imagineers in the 60's imagined the "future" to be like? I've heard that somewhere, or that's the assumption I got from the ride itself.
If that's the case, of course the clothing of the characters and the technology would seem irregular! It was based on their theories of how the future would look. It's not like they had a crystal ball in 1960 and could know exactly what the future would hold for fashion and technology.
To be honest, the inconsistencies between the "imagined" future and the "actual" future (today) is what makes this ride so great! I think it's interesting to see how people imagined the future. It's also one of the reasons why this ride has hung around for so long: it's timeless! It's the same ride that guests rode when it was first constructed, but it's still relevant because now we can ride with a new perspective.
I know this thread was meant to focus on things that bug us about the parks, but I felt like I should stick up for this ride and its original creators.
