EPCOT as envisioned by Walt Disney was to be an actual city where people would live and work. He designed it in concentric rings, somewhat resembling a wagon wheel with spokes. The inner zone would have towers and was supposed to be where people work. The middle ring was a park and retail area, and the outer-most ring was residential. Walt Disney had the idea that all major American corporations would want to relocate their R&D to EPCOT, so if you could get GM next door to GE and might get an electric or atomic car sooner. So was the thinking. The conceptual designs had a very mid-century futuristic look to them. Walt Disney even proposed covering the city in a dome, so the weather would always be perfect. But I'm a bit skeptical about being able to keep a dome cool and dry in the Florida climate.
