Spindle and hourglass-two perfect models in the world

The spindle returns one to both ends, and the hourglass returns one to the center. It is perfect and perfect. The OSI Network Model eventually becomes an hourglass, And the IP address becomes a point, while the history of the world becomes a spindle. At the beginning, civilization was generated from one place and then divided. Now it is globalization. It can be seen that if one thing is scattered at the beginning, it would be an hourglass model that forces everything to be taken together, but the strength of nebing still separates everything, in turn, if they are unified at the beginning, they should eventually be unified even though they have gone through hardships and fallen apart. The first problem facing OSI-TCP/IP is device heterogeneity. Applications are becoming increasingly richer and increasingly uncertain. Although people have already recognized the Internet addressing protocol, application layer protocols seem increasingly chaotic, although ASN1 has solved some of the problems, I believe there will be new problems. Let's look at the Jews, who are rooted in the fertile land near meushodon Damia at the beginning. They suffered three thousand yuan in hardships, it is still very united till now.
People seem to have an idea like Yijing. If a thing is too scattered at first, it cannot be further dispersed. So they set rules to try their best to shrink them, so they gradually get back to it, at last, however, to another extreme, it may be that the dispersibility of the inspector is in the stem, so it is scattered again. For a long time, it must be combined for a long time. This is the hourglass; if one thing begins to be centralized, people's power will be dispersed, and nebing's normalization attribute will be added. As a result, it will contract after the extremes of decentralization, this is the spindle. It's boring or amazing. But I always believe that the hourglass and the spindle can be combined into a more perfect form, that is, the saddle!
