Abstract
The author claims that the Intenet may have serious side effects in decrease of high-quality contents and degradation of ability of thinking and making good human relations, especially for younger generation. First, Internet-related applications moves advertisement income from contents making sector, such as newspapers, TV stations, CD producers/sellers, and publishers, to platform sector. This may cause loss of best quality contents we have now. Second, the Web contents with their hypertext form may shallow our ability of thinking and obtaining systematical knowledge, as well as weaken human relations and make our society a mixture of mutually exclusive groups.
