There once was a time when humans could only leave their descendants things that were physical, but this is no longer the case. More and more of what we cherish is no longer material in nature, but rather informational. And even though modern humans tend to store everything online, this is also not the way to go. My eldest daughter has my grandson's photos and movies in some online site, but what happens if that company goes out of business?
A guy like @BrianRoemmele on X keeps hammering it in, and rightfully so: current web based AI is trained on unfiltered garbage mostly, and then coralled into doing what its masters want by humongous system prompts. Hardly the kind of system that "knows you"! Meanwhile not even five percent of physical information carriers have been digitized, which means an awful lot of true history is being forgotten and watered down by the stories that current writers of history claim happened.
For instance, I still have here a box full of my grandfather's poems. He wrote them in the dialect of the southern islands of the Netherlands, a province called Zeeland. I remember well having memorized the one he wrote about his life as a farm hand, in order to perform it in front of the class. That was many decades ago, and I don't think it was ever spoken out loud since...
So if anything, I'd like to keep all of that for my family, but being a software developer first, I am also thinking about project Heritage, a software system to keep such information properly stored. More on that later...
