Remembering what numbers your favourite football players wore in 1995, the capital city of Latvia, Moldova and Belarus are and all the lyrics to about 3 or 4 songs is not knowledge. It is storage of data, and the data is man-made, or arbitrary tags. it’s what Google does.
Now, I don’t know what knowledge is but I think the general idea of what being smart is has nothing to do with Google. If you can Google the answer, that is not intelligence.
Intelligence comes from a knowledge on how to live life. Fully understanding that all you need to live are food, shelter, water and oxygen. And living it.
Not getting stressed about anything other than that, in any situation at all. That is intelligence – Understanding how to live.
