Recently, Microsoft co-founder Bill Gates predicted in a podcast that the proliferation of artificial intelligence technology will profoundly change our way of life and work, and that earphones and smart glasses will become two key areas of AI hardware. Gates believes that earphones are not just audio playback devices, as they will add audio capabilities, eliminate noise, enhance sound quality, and become an important medium for human-computer interaction; smart glasses can project video content into the user's field of vision, opening up new forms of human-computer interaction. The development of these devices will enable personal intelligent agents to surpass traditional human assistants, as they can track and read content that interests users and provide continuous assistance. He pointed out that although we have already revealed a lot of personal information in digital systems, the value of artificial intelligence assistants would be enormous if they could summarize meetings or assist in follow-up matters.
