Do you know? Why are so many smart people in this era frantically recording themselves? Because in the end, AI competition isn't just about computing power or knowledge, but about who has the "real person." The "real person" can be understood as: not an account, not a label, and not a bunch of resume information, but a "long-term stable, understandable personality." What AI lacks most is not knowledge. Knowledge is almost limitless now. What it truly lacks is: a concrete person, how they think, how they judge, and how they react. Some will get angry; some will sneer; some will prioritize interests; some will emphasize morality; some instinctively oppose authority; some naturally pursue order. These things are what make a "person." The most important thing in the future is not "information production," but "personality sovereignty."
