Well if we want to take it to it's extreme end, death is a certainty. At some point all nature will decay and the universe and all energy will stop, it will all be used up. Nature will be used up and gone, barring the supernatural we will be too, so at that point even if we become naturally immortal we will die, because nature and more importantly energy will be no more. At this point Tesla, Newton et. al. will not matter, not a thing will matter, because the universe will be dead. So if we die in 85 years or x billion of years the final result is the same. Death is part of life and at some point even our contributions, no matter how great they are will be of no value. The old wisdom nothing last forever is true.
