What would Musk's $1-trillion net worth look like?

Elon Musk's net worth could surpass $1 trillion if SpaceX's IPO sails through successfully. His net worth would then be more than the economies of all countries in the world except 20 and could help fund UN initiatives to end world hunger for 25 years. He could spend $1 million/hour and still take 100 years to exhaust his wealth.
