In today's world, more and more convenient products are being developed, but just how convenient will they be? Sometimes I get scared.For example, 20 years from now, there may be many people who spend their days without moving from their computer. I take classes at school in front of a computer, and the computer automatically cooks and prepares breakfast, lunch, and dinner for me. I'd hate to live in such a world, but considering the current evolution of personal computers, I don't think it's just a fantasy story. The spread of the Internet has ushered in a convenient era where networks can be connected almost everywhere.
