Stepping in to fill the void is the the pink Mekon Jeff Bezos, who thanks to a surge in the value of Amazon.com has became the world’s richest bloke.

Shares of the online retailer fell 0.7 percent to $1,046 at 4 p.m. in New York, after climbing as high as $1,083.31 four hours earlier, which gave Bezos a net worth of $92.3 billion. Gates had a net worth of $90.8 billion.

Bezos remains ranked second on the Bloomberg Billionaires Index, behind Microsoft's Gates, 61, who has held the top spot since May 2013.

Gates has been spending his fortune trying to work out how to wipe out the mosquito and cure all sorts of nasty African illnesses. Bezos spends his money on property and putting rich people into space.

For example, he owns a top-of-the-line, $65 million private jet, the 2015 Gulfstream G-650ER, via his holding company, Poplar Glen, says Wealth-X. The model is the "longest range business jet" and has a top speed of Mach .925, according to the Robb Report.

Inside a mountain on Bezos's property in Texas, workers are constructing one of several 10,000-year clocks. The clock, which is meant to run for 10,000 years, is the brainchild of The Long Now foundation, and Bezos has invested a reported $42 million into the project.

To be fair Bezos has allocated some of his wealth to charitable causes. In May, Bezos gave $1 million to the Reporters Committee for Freedom of the Press.

In in 2015 the Bezos Family Foundation had more than $54 million in assets and donated more than $20 million. Recipients include Teach for America, the Oprah Winfrey Leadership Academy, the Long

Now Foundation, Aspen University and Woodland Park Zoological Society. Bezos also donated $2.7 million to the University of Washington Foundation (2013), $2.5 million to Washington United for Marriage (2012) and $15 million to Princeton University.
