I actually came up with a possible alternate ending that I think would have been better than the ending we got. In my alt ending, when our main characters land on tomorrowland in the apollo capsule, they don't find a wasted place. Instead, they find a technologically marvelous place a lot like the pin vision that Casey saw. We get to see a lot of tomorrowland. We see limitless clean energy, safe automated transportation, amazing virtual reality entertainment, educational system that is tailored to each person's personality in real-time, etc... Casey wonders why these technologies are not shared with Earth in order to make a difference. Frank explains that during his stay, an ideological rift occurred in Tomorrowland. One camp wanted to share the technology to help earth. He was exiled because he supported that camp. The other camp, led by Governor Nix, believed that Earth was inevitably doomed, so tomorrowland should focus inward, keep its tech to itself and make sure it continues to prosper. Casey agrees with the first camp and starts speaking up. We see that tomorrowland has a darker side. People are relunctant to speak their mind. Flying drones spy on everyone. Nix has a police state hold on tomorrowland. Everyone is happy as long as they agree with Nix. Frank, Casey and Athena meet up with the underground, those who agree with the first camp that technology should be shared, and they lead a revolt against Nix. After a struggle, Nix is defeated and tomorrowland ceases to be a police state and much of the amazing technology is introduced to earth, albeit slowly so as not to shock people. We see clips of TED talks, and someone looking like Elon Musk introducing the next Tesla product.
