□ Northwest Tuk: A wise man described the future of human society with a "smart earth". So what exactly is a smart earth? Experts gave the formula: Internet plus Internet of Things = Smart Earth, and pointed out that more thorough induction, more comprehensive interconnection and deeper intelligent insight are the three driving forces of a smart Earth. Take a smarter tracking system as an example to illustrate the power of wisdom: IBM and Norwegian Matiq company are developing more advanced food tracking solutions, using RFID (Radio Frequency Identification) technology to track meat and poultry food from farms to supermarket shelves and supply links, so as to ensure that food is in the best state, which is the benefit brought by wisdom. The future is green, and the future is wise. Facing the smart earth, the library should also develop in the direction of wisdom, and finally it really needs the wise people in the library industry to think and study. Comments: It can be seen that wisdom and service complement each other. When wisdom reaches a certain level, service will naturally go up the ladder, so "service" can never be improved only by enthusiasm.
