A gear that does not conform is a wrench in the works.
Remove the gear until it can be brainwashed, retrained, forced to mesh.
How to fix it?
How to force it?
The hammer?
Not a surgical tool, by any means, but this isn’t a surgical processus.
Accuracy requires thought.
The bludgeon is a much simpler tool.
A simpler weapon.
Certainly not as successful as perhaps another, but casualties are to be expected in such lock-step, industrial machinery.
It was the height of modernity a century ago -- but the world is changing, and the machine is grinding slowly into the primitive darkness of archaism.

The world is changing. Rearranging.
More and more gears are dropping from their cogs into the morass of the behemoth.
More and more are getting lost in nauseous darkness.
More and more gears.
More and more wrenches in an aging, beastly, anachronic and inefficient monstrosity.

Something’s gotta give.
