Bill Gates is known for being one of the world's biggest optimists, in addition to one of its largest philanthropists. But Gates is concerned about the impact if the U.S. follows through on plans to cut foreign aid.
"Overall like Warren Buffett I am optimistic about the long run," Gates said during a Reddit AMA (Ask Me Anything) forum. "I am concerned in the short run that the huge benefits of how the US works with other countries may get lost. This includes the aid we give to Africa to help countries there get out of the poverty trap."
Gates, who has said the idea of a "robot tax" is worth exploring to slow the pace at which human jobs are automated, says the notion of a guaranteed basic income probably isn't an option — at least for now.
