Someone said, Morris, you post so many messages every day, most of which are just taken from others? Actually, he's not wrong. The vast majority of human knowledge is originally obtained from others. No one can create information out of thin air; the news, data, opinions, and stories we see are essentially flowing between people. But information has never been the value itself. The same information, some forget after reading; some can filter; some can filter but cannot judge; some can judge but cannot track and iterate over the long term. What truly widens the gap between people is never what they see, but how they understand, verify, connect, and update that information. So what I share may not be the value of the information itself, but my understanding and iteration after continuous observation of these pieces of information. Information is public; cognition is private.
