Just so we're al clear: if the leadership at Disney is willing to do this, they are willing to do much, much more.
At risk of sounding ultra-dramatic, it truly is over. And I don't mean that these parks can't be enjoyed by families (they will be). Nor do I mean that every historic aspect of these parks will be gone overnight.
What I mean is that today's dopamine addicted society has convinced Disney that the historic values and ideas that were the bedrock of these parks are no longer important or valuable. I don't know how long it will be but one day, every last facet of these ideas will be gone and Walt Disney World will be indistinguishable from Universal Orlando. My guess is about 20 years left before it's all gone.
