I'm referring to the "technology" that allows guests to understand the speech of fish. Since this and the idea of discovery are the center thematic concepts of the ride, it fully fits in Tomorrowland.
The Submarine Voyage takes us on a futuristic journey through liquid space where we will one day be able to understand the languages of fish and be captivated by the stories they will tell.
Are the Subs not futuristic because fish won't exist in the future? Is it because understanding fish speech is too futuristic? Is it because animated fish are less futuristic than fish that look realistic today?
Or is it because the timeless tale of Finding Nemo perhaps takes place in the present, despite the obvious employment of futuristic technology on the ride?
