What I am saying is absolutely true. Future generations will think about you, just as you think of people who have passed long ago.

Think of all the generations of your direct heritage that you are totally unaware.

If Bob discovers a cure for a terminal illness saving thousands of lives, is his life and achievements rendered meaningless if future generations have forgotten about him?

Is it 'meaning' or 'ego' that necessitates being remembered?
