The whole idea is to show the progress within a lifetime, so I really hope that instead of updating it they restore the final scene to its original form, with historical context, and maybe an aftershow exhibit of progress since the time of the show. Yes it's far more appropriate for Epcot than Tomorrowland, but it is where it is.
Or, have a new final scene set in the 1960s or 1970s, where they hint at the dawn of computers, and who knows what the future will hold, with some nods to the oncoming technological revolution. That way you keep the time gaps consistent, don't need to update it regularly, but still works in the context of the modern digital age.
