  • Artificial Intelligence (AI) could transform economies, politics, and everyday life. Some experts believe this increasingly powerful technology could lead to amazing advances and prosperity. Yet, many tech and industry leaders are warning that AI poses substantial risks, and they are calling for a moratorium on AI research so that safety measures can be established.
