Answer:
Intentionality.
Explanation:
Intentionality is a crucial mental phenomenon that analizes perception, action, causes, meaning, references, etc. John Searle states that, machines lack intentionality given that they do not have the proper material substratum required to sustain whatever causal powers that are minimally sufficient to produce intentionality. Human brains have them, other life forms may as well, but no machines during that time's market did.
