Disney's evolution of Tomorrowland/EPCOT reflect the three phases of futurism since Asimov's essay. In the early 20th century the future was about more fantastic machines- rockets, super-cars, better home appliance. The Tomorrowland Rocket to Mars ride embodied this. But young people became disenchanted with the pollution and militarism of hard engineering in the 1960s and turned their attention to the biological sciences on Earth Day 1970. The future was about ecology, sustainable living, commune type socialization, etc. The EPCOT dome ride embodied this vision of the future. Then came personal computers, video games, special effects movies, the internet and mobile. The future shifted to an information rich world. Now younsee lots of computer screen exhibits in Tomorrowland.
One of the best inspirations you can get for what you could build to score a home-run is to read science fiction. The older the better in a way, because those ideas may be <i>just</i> viable today. In general reading is a great source of inspiration but SF has a special place in that it is forward looking by definition and has/had some pretty creative people doing all the groundwork.
