This new AI tool from Google could change the way we search online

What does the future of internet search look like? Google envisions it as looking more like a casual conversation with a friend. While Google's search engine has been online for over two decades, the technology that powers it has been constantly evolving. Recently, the company announced a new artificial-intelligence system called MUM, which stands for Multitask Unified Model. MUM is designed to pick up the subtleties and nuances of human language at a global scale, which could help users find information they search for more easily or allow them to ask more abstract questions.
