In Sapiens by Yuval Noah Harari, it is mentioned that
Chaotic systems come in two shapes. Level one chaos is chaos that does not react to predictions about it. The weather, for example, is a level one chaotic system... Level two chaos is chaos that reacts to predictions about it, and therefore can never be predicted. Markets, for example, are a level two chaotic system.
In the field of chaos theory, are 'level one' and 'level two' chaotic systems real descriptors? I could not find any information about such labels aside from a few blogposts. Or, did Harari make up his own descriptions and use chaos theory jargon to justify it?
