Walt had the privilage of building Disneyland in a time where details were appreciated more, kids didn't grow up so fast, and companies weren't always taking shortcuts simply to improve their bottom line.
But what if Walt was born 10 or 20 years ago? For the sake of conversation, lets assume that everything about him is the same except for the society and technology around him (he still creates mickey mouse, wants to build DL, etc.). What would be different and what would be the same? Would DL be as magical as it is, or would it be a commercial mess of sorts?
