In a recent article, Bill Gates believes that the new type of intelligent software, Agent, will revolutionize the way we interact with computers, transforming the software industry and bringing about the most significant change in the computer field since the transition from command lines to icon clicks. Agent can understand natural language and actively complete tasks based on a deep understanding of the user. It will make services such as healthcare, education, and productivity more accessible and become the next big trend in the software industry. However, Agent also faces significant technical and social challenges related to privacy, security, and ethics. Gates calls on relevant businesses and policymakers to address the impacts of this new technology.
