Go with the Turing Award if you want to be remembered.
> Forbes magazine updates a complete global list of known U.S. dollar billionaires every year. John D. Rockefeller became the world's first confirmed U.S. dollar billionaire in 1916
If you want to play, note that I did not say USD anywhere in my comment. Not to mention that Forbes was founded in 1917, and so it clearly has no data collected to "confirm" an earlier billionaire. We can go back to the 14th century if you like (https://www.wikiwand.com/en/Musa_I_of_Mali):
> During his reign Mali may have been the largest producer of gold in the world at a point of exceptional demand. One of the richest people in history, he is known to have been enormously wealthy; reported as being inconceivably rich by contemporaries, "There’s really no way to put an accurate number on his wealth" (Davidson 2015).
But thanks, I actually never knew that about USD billionaires.
Anyways, it was just an example.
