About being forgotten:
There is a good fiction book in Russian on the topic: https://ru.wikipedia.org/wiki/%D0%A1%D0%B2%D0%B5%D1%82_%D0%B...
Plot:
After you die, you get to another place, call it heaven.
Every time someone who is alive remembers about you, you get a coin.
Coins are used in this afterlife community for food, entertainment, labor, etc
You cannot steal them, although can give as gift to another afterlife person.
Of course, in the beginning you are rich, people miss you. Then income drops...
When you are out of coins - you die second time, most likely forever.
Well written, good plot, etc.
But! In this after world Hitler and cavemen whose body is part of the exhibition in natural sciences museum live better and longer than any "normal" and "ordinary" person, especially in the long time perspective.
P.S. You still can do many things in this world to make people remember you for a long time after you are gone.
