So this take is very Defunctland, but here goes.
I think Disney has developed in more or less precisely the opposite the direction in which Walt wanted. Towards the end of his life, he was clearly not very invested in animation/Disney branding and really wanted to be remembered as a great industrialist and unifier, like Henry Ford but with information. This is clear for the following reasons:
- Disneyland, basically the last big project that Walt completed before his death, doesn't have that much Disney branding. Jungle Cruise, It's a Small World, Haunted Mansion, Tomorrowland as a whole, basically everything outside of 2-3 rides in the Castle itself.
- EPCOT wasn't supposed to be an amusement park, but rather a model city with multiple layers, with residential and business on top and all the car infrastructure on the bottom. Basically it was designed to be Midgard from Final Fantasy VII, but real.
- Walt Disney supposedly made remarks in private to the effect that he didn't want to be remembered as a cartoonist, like "Imagine being remembered for inventing a cartoon mouse!"
All this taken together makes it seem like Walt Disney corporation basically exhausted the creative possibilities of the mediums it's known for today, cartoons and amusement parks, way back in the 1950's and 1960's, and wanted to move on to the next step, city building and molding society as a whole. Kind of makes you wonder what would have happened if Walt lived another 15 years and managed to build his pie in the sky.
