Microsoft founder Bill Gates, who is believed to be worth around 86 billion, told an audience at the Misk Global Forum that advancements in robotics and artificial intelligence (AI) will help improve efficiency in a range of industries. Speaking at the forum in Riyadh, Saudi Arabia, Mr Gates said: "We are in a world of shortage, but these advances will help us take on all of the top problems." "We need to solve these infectious diseases...We need to help health care workers do their job." The 62-year-old business magnate believes AI will transform the working environment in countries across the world and could eventually be used to help with social care and education. He continued: "As we free labour up from things like manufacturing, we can shift it to some of these very human-centric needs."
