Considering the theory of everything which states that everything is possible. Is it logical to assume that since science has no boundaries, people in the future will be able to reincarnate those who contributed the most to humanity? as they possessed best genetical variations in their DNA?( although not necessarily, since psychology (although having some correlations with DNA) plays the key role in determening the ability to succeed of a person). I think this concept has to be educated in our society as it can replace the need to believe in god. Instead, : " if you do something great to the humanity, you are worth being brought back to life when time comes"
