I don't know about that. This year they're both the same age, had both amassed billions, and had become titans of industry. One of them publicly devoted himself to spending his riches on improving humanity; the other continued to enrich himself by developing what are at their core expensive first-world gadgets (though how much he gave to charity is I believe not known).

How much does it take before you have a "full life" that you can be judged by?
