None of my business but I think you're overreacting to the point he's making, It's the same as living through the 60's and studying them later, it's just a different experience.
Years from now they will still remember 9/11 but those of us that lived through that have a totally different experience, like my parents when Pearl Harbor was bombed. There are historians that have studied Pearl Harbor and are more informed and knowledgeable than most of the people who lived through that but the experience level is completely different.
I have watched the Ice Bowl and the Emmitt game several times but nothing matches the emotional experience of the first time through them, what's missing and can't be recaptured is the drama of the moment. Bart Starr going over Jerry Kramer is interesting now; it was devastating then.
There are just moments in time that are truly "you had to be there".
