On a personal level, I have regretted not listening to my grandfather and father when hey were telling stories of their youth. They were not important people to the rest of the world but had some great stories of their upbringing and life.
We who can still tell the stories of our youth should do so, this blockchain being eternal is the perfect place to put them.
Our great x 10 grandchildren could come here and learn what life was like in our day.
How many kids of today can imagine a life without a mobile phone to fiddle with, computer games to play with etc.
Someone else's story will prompt the memory cells and we would have a large collection of 'History', may be no 'platos, but at least something for your upcoming kids to read.
We already have the schoolers meeting and discussing things, so we are part way there.
