Gates is also mortal, although some of his admirers may find that hard to believe, and as they say, there are no pockets in shrouds. So he is now engaged in the process of ridding himself of all that money in the hope of extending the lives of others less fortunate than himself.
“I’m certainly well taken care of in terms of food and clothes,” he says, redundantly. “Money has no utility to me beyond a certain point. Its utility is entirely in building an organisation and getting the resources out to the poorest in the world.”
That “certain point” is set a little higher than for the rest of us – Gates owns a lakeside estate in Washington State worth about $150 million (£94 million) and boasting a swimming pool equipped with an underwater music system – but one gets the point.
