Robot. Zombie. Apocalypse. (Not-So-Cold Storage as Chekhov's Gun)
We all agree that the cooling malfunction of the cold storage is definitely going to be a thing. We know the purpose for the cooling is to prevent rotting from Stubbs' warning about the smell. We know that they fully wipe malfunctioning hosts before they are put in storage. We know that any reaction to injury in hosts is purely a "psychological" response, not an indication of the hosts ability to continue functioning. Essentially, we know that malfunctioning, mindless, rotting hosts are living in the basement of the Mesa Hub.
Let's break this down again:
Rotting flesh + mindless bodies + impervious to injuries aside from destroying or removing the head.
What does this sound like to you?
I'm pointing at the fences now that we're going to at least get one robot zombie horde storming up Mesa Hub towards Mesa Gold scene. It might even be a proper plot point that if a "waking" AI doesn't get to the maze in time or is wiped, they will go full murder mode.
I apologize if someone has already mentioned this, but it hit me spontaneously when I was reading the thread about how WW operations are a total mess.
