More of an end credits, really. 0.5 leads straight into ‘Tomorrow’, but 0.6 follows up quite a long time afterwards. After the Simulation, after the Revolution, after the Satellite, after… everything.
In terms of actual vs fictional 1980s theming: while 0.5 was sort of inspired by Walt Disney World’s Tomorrowland and EPCOT Center, this one is the 1988 Global Forum of Spiritual and Parliamentary Leaders on Human Survival.
