I guess its not clear to me that's all they do? I mean, from the perspective of the anthill outside my door, I probably seem very rigidly programmed. I walk past on a fairly set schedule and always in the same basic pattern, but that's an accident of perspective, not anything else.
Yeah...if the MCU continues in that direction I'm likely to either be a lot more selective in which of the MCU films I go to, or just cut back altogether as I really dislike that trope and the further away from the person on the ground the less I care.
