Timnit Gebru and the fight to make artificial intelligence work for Africa

The way Timnit Gebru sees it, the foundations of the future are being built now. In Silicon Valley, home to the world's biggest tech companies, the artificial intelligence (AI) revolution is already well under way. Software is being written and algorithms are being trained that will determine the shape of our lives for decades or even centuries to come. If the tech billionaires get their way, the world will run on artificial intelligence. Cars will drive themselves and computers will diagnose and cure diseases. Art, music and movies will be automatically generated.
