So in Tomorrowland many of the world's dreamers and geniuses get sequestered away in a utopia where they work together to create some amazing stuff, such as
anti-aging drink, great AI and robots indistinguishable from humans (even in the 1960s!), control of gravity, casual interstellar travel, tachyon-based engineering, portal technology, etc.
So my question is:
We could use all that stuff in the regular world. Why the hell aren't they piping these discoveries back to us? How is it good to rob the world of its geniuses and not give back their discoveries?
