How will Mark allocate his $45 billion in charitable giving?
Considering that Mark has previously expressed interest in living forever, it would be very sensible for him to donate large amounts of money to SENS.org, the leading organization that is working on Indefinite life extension.
Also, considering that aging is the largest cause of sickness and suffering on the planet, SENS Foundation is also the clear winner in terms of effective altruism.
I hope Mark chooses wisely. But regardless of where the money goes, we should thank Mark for his generosity.
