Want to verify if you're a real person? It seems simple, but in fact, it leads to a paradox. Suppose we set a certain standard as the 'only proof of humanity'—AI will learn to meet this standard—and then we find that the standard has become invalid. The boundaries of public opinion are torn apart. The problem is that any verification method we can think of can potentially be exploited in reverse. AI is becoming smarter and smarter; they will imitate, adapt, and evolve. We create rules to distinguish ourselves, but they find ways around these rules within the framework. What does this arms race ultimately lead to? The collapse of the standards themselves. The line between real and fake becomes blurred.
