Go-automatically build a knowledge system

Now, I often hear or see such a word as system/architecture. I think there is a reason why something can be seen in this way. So I think there should also be a system of knowledge. Otherwise, how can there be so many subject systems and so many disciplines and specialties. Since knowledge has its own system, how can we build our personal knowledge system. By memory? What if our memory disappears one day? Is this kind of knowledge architecture also about to disappear? It seems that we still need something to help us save the knowledge system we have established. If we have not yet built our own knowledge system, so what tools should we use to help us build our own knowledge system.

Well, it looks like a good idea!

A tool that helps us build and save our knowledge system!
