The evolution of entry points fundamentally changes the competitive landscape. In the internet era, there might be 1,000 entry points; in the mobile internet era, possibly 100 entry points; and in the AI era, perhaps only 10 entry points. This means that the winner-takes-all scenario will become more severe in the AI era, with underlying logic being: further concentration of capital and resources, technological barriers and economies of scale, data network effects, platform and ecosystem lock-in, iteration speed, and first-mover advantages. The familiar "80/20 rule" may truly be rewritten as the "99/1 rule", where 1% of companies and products will capture 99% of the market, value, and market capitalization. In the secondary market, differentiation will become more pronounced, with elephants not only able to dance but also to take flight. For secondary investment, one must adopt a leading company mindset, as the second or third-tier companies are merely mediocre. One should invest in strong companies, high-speed growth, and those with monopolistic competitive advantages.
