When generations start being replaced by following generations, what is important changes as well.
You can even see it on antiques road show. You see the shift in what is valuable now vs twenty years ago. Even old farm tractors value has changed. As our generation declines so does what we thought was something that needs to be preserved no longer is considered important.
WW2 interest is mostly left to the historians as we die off. 911 is soon to follow I am sad to say.
Sadly too as all of this slips away under the cry new apps are for the cellphone glued to the eyes of the recent generations. Equally as sad is the term "Smart Phone" in the hands of those that are so poorly educated.
AH is only valuable to us still alive from our generation. The good news is we still like blowing each other up. That is not going to change as long as we can hold a joystick inside our finger's grip.
