• Microsoft billionaire Bill Gates announced that he will give away "virtually all" of his wealth over the next 20 years.

Billionaire Bill Gates announced on Thursday that he will double his charitable giving to $200 billion over the next 20 years.

In a , the co-founder wrote that he was motivated by the many challenges facing the world, such as children's health and climate change, as well as the late Andrew Carnegie's admonishment of wealth hoarding.

"People will say a lot of things about me when I die, but I am determined that 'he died rich' will not be one of them," Gates wrote. "There are too many urgent problems to solve for me to hold onto resources that could be used to help people."

Gates is currently the world's fifth richest person with a $168 billion fortune, according to the . The $200 billion commitment assumes his charitable foundation's endowment will grow through investments.

Gates is one of few billionaires to publicly step up their charitable giving as and reel from federal funding cuts. Despite his increase in giving, he said philanthropists cannot cover the multibillion-dollar foreign aid cuts by the U.S. and other wealthy countries.

Musk has signed the Giving Pledge. Gates told the that he doesn't know whether Musk will follow through.

"The Giving Pledge — an unusual aspect of it that you can wait until you die and still fulfill it. So who knows? He could go on to be a great philanthropist," he said before pointing to Musk's involvement in the foreign aid cuts.

Musk has given away less than 1% of his wealth, according to . The publication estimates his out-the-door giving — gifts that have been paid, not just pledged or parked in a foundation — at $620 million over his lifetime through 2023.
