PLAYBOY: Does your net worth of multi-billions, despite the fact that it’s mostly in stock and the value varies daily, boggle your mind? GATES: It’s a ridiculous number. But remember, 95 percent of it I’m just going to give away. [Smiles] Don’t tell people to write me letters. I’m saving that for when I’m in my 50s. It’s a lot to give away and it’s going to take time. PLAYBOY: Where will you donate it? GATES: To charitable things, scientific things. I don’t believe in burdening any children I might have with that. They’ll have enough. They’ll be comfortable.
