Wow. It boggles my mind to think about how rapidly things have changed. As an extremely strong proponent of wokeness - bc wrong is wrong, regardless of time period - I also get how culture takes a moment to digest the changes happening all around us.
For example, 1974 wasn’t all that recent, but those 50 years ago seems so much more so than e.g. the 1920s of 100 years ago, in large part due to being able to see it on Television (even with wacky coloration & such:-). Every aspect of life - like taking a horse or walking rather than Uber or subterranean Metro - has changed since the 20s, but also a lot has changed since the 70s too. And even the people who lived through it may not realize all the various ways how.
