this is a great question.
i'm assuming that you are asking about contemporary individuals.
if i'm wrong and you are taking into account people of all time then please correct me.
i'm a big fan of Dan Carlin and he describes people who have made their mark on history as "Historical Arsonists".
these are people who have destroyed on a massive scale allowing something new to arise from the ashes.
but then you have your Di vinci, Einstein, Picasso...they will not be forgotten.
who is alive today that will be remembered 1000 years from now?
i don't know.
