Do you ever feel that the world is really moving too fast? Humanity is still studying war, power, and human nature, while AI has already begun to reconstruct the very fabric of the world. They are so fast that—rules haven't been fully understood yet, they are already being executed by the system; meaning hasn't had time to settle, and people are pushed forward. Everything is accelerating, yet very few have time to stop and ask: where are we really heading? Think about it carefully, as an ordinary person among humans, perhaps learning to be happy has become a core skill that is increasingly rare and yet more and more important.
