One of the key principles of money is ‘opportunity cost.’ It means that when I buy something, I have to give up something else in return. We think we buy because we need something, but we often forget that we could buy something else instead. We rarely consider ‘opportunity cost’ when making a purchase. We do not compare other values against our needs. Buying something means giving up something else, but we often don’t realize it. When we spend money, we should also consider the ‘opportunity cost’; yet, in reality, we aren’t trained to do so. By making a purchase, we bypass the value comparison that may not offer any additional benefits. Maybe it’s because we lack knowledge, or perhaps the idea isn’t appealing. - Joseph’s “just my thoughts”
A Korean AI company developed a language-learning AI for a 5-year-old, splitting it into two systems: one displaying only children’s videos and the other showcasing YouTube videos. After two months of learning, the company was eager to assess the results. They found that children using YouTube, with fewer restrictions, had better language-learning outcomes than those who watched only children’s videos. This raised a thought in me: parents’ efforts to protect their children from certain influences may stem from an unreasonable desire. Striving for perfection can feel woefully inadequate in this world. Isn’t the essence of education about equipping individuals with the knowledge of right and wrong and guiding them to maintain their humanity? - Joseph’s “just my thoughts”
