"AI tycoon" Li Yizhou had his account suspended for selling AI courses allegedly filled with false advertising, sparking discussions about the chaotic state of the knowledge-paying industry. Many bloggers have seized the opportunity of the booming AI technology to launch expensive training courses, reaping the benefits from anxious users. A significant number of AI courses on the market are low in value and lack substantial content. Instead of purchasing these courses, it would be more beneficial to learn and practice on one's own. Ordinary people should understand that it is impossible to master AI through a few hundred yuan's worth of courses, and dreaming of making big money through such means is nothing but wishful thinking.
