> Maybe that mindset changes when you're a multi-billionaire,

I've always thought the rich man who doesn't want to die and is desperate to beat it with wealth as a cliché actually, a sign of the ultimate hubris of being wealthy. Desperate to forestall death while others are having a hard time living. Death is the great equalizer, rich and and poor die alike, but in the future I guess the rich will even escape death while some of us cheer them on.
