The podcast discusses the idea that **when many people pursue the same knowledge for financial gain, that knowledge eventually becomes a commodity**. This means the knowledge loses its uniqueness and becomes subject to price competition. This concept is illustrated through the example of lawyers in Japan; while their qualification was once a guarantee of success, the increase in their numbers has made it harder for them to stand out.

The podcast draws a parallel with the story "The Spider's Thread" by Ryunosuke Akutagawa. In this story, a man in hell is given a chance to escape via a spider's thread. However, he selfishly attempts to prevent others from following him, which causes the thread to break, condemning everyone. This mirrors the competitive nature of business where individuals flock to what seems profitable, turning “blue oceans” into “red oceans”.

The discussion also touches on how trends like AI are likely to face the same issue of commodification. The podcast ultimately argues that **learning should be driven by personal interest rather than solely by the prospect of making money**. If knowledge eventually loses its market value, it is better to pursue what is personally meaningful. The key message is that **knowledge pursued purely for profit is prone to commodification**, making it less valuable, and that finding meaning in learning is important, regardless of market trends.
