When COP made it's debut in 1964, everyone in the audience could identify with one of the Acts because they lived through it. Act 4 was modern day 1960s if not just a little bit into the future, possibly 1969. When it moved to Disneyland in 1967, it was still relevant and not entirely outdated. When it moved to WDW in 1975,it needed and got a proper update to once again reflect the last scene in the current decade as the present if not just slightly in the future. It was updated again the early 80s as well. When Tomorrowland was redone in 1994, COP once again got it's proper refurb bringing the current scene to the present day early 1990s (which did have some 80s flavor still) but with touches that suggested the year 1999.
The current COP represents the following years:1904 (1904 world's fair), 1927 (charles lindburgh), around 1946ish (television), and then 1999 (new century ahead).
The problem is that current audiences don't connect to it because only those 65 and older might have lived through the first three Acts, while even today those under the age 15 see the last scene as a dated look at the future. It seems familiar, but old at the same time. COP didn't get it's properly refurb in the 2000s or the 2010s yet to bring that last scene up to date. Even then, there is so much disconnect with the previous Acts that it may not make sense. Why would they skip over the 1950s through 2015?
So today, the attraction serves more as a museum piece. COP is one of my favorite attractions as well. I couldn't stand to see the first 3 acts destroyed or the attraction removed, but it does need an update.
I've said it a few times on here, the best way to bring this attraction back is to show the progress of computer technology vs. electricity. Act 1 could be the mid 1960s representing the what the world was like when Walt left us. Computers were huge and there was lots of technology to showcase from that era. Act 2 would be 1984 when personal computers were starting to arrive in homes on a larger scale. Video games were shifting from the arcade to the home. There had been changes in media and electronics, appliances, and society. Act 3 would represent 2000, a time when many were optimistic about the new millennium and we had the rise of the internet, cell phones, and new electronic devices. Act 4 would bring us to 2020. Somewhat current, somewhat in the future.
The audiences would once again identify with the scenes as they would have lived through them again. We don't think of our devices as much as electronic as they are digital. Almost everything has a tie to a computer these days. The time jump won't be as crazy, and the attraction would breathe new life.
