abramdemski comments on Agent Boundaries Aren’t Markov Blankets. [Unless they’re non-causal; see comments.]

I don’t understand. The fact that every single node has a Markov blanket seems unrelated. The claim that the intersection of any two blankets is a blanket doesn’t seem true? For example, I can have a network:

a → b → c

| | |

v v v

d → e → f

| | |

v v v

g → h → i

It seems like the intersection of the blankets for ‘a’ and ‘c’ don’t form a blanket.
