Reliable quadruple turrets and a new arms race

How would navies react if reliable fourteen-inch quadruple turrets put twelve guns on a battleship?

They would be alarmed and would quickly pursue their own escalation, probably toward four triple sixteen-inch turrets.

In the naval-design scenario raised from Twitch, a battleship with three reliable quadruple fourteen-inch mounts would have a twelve-gun broadside. That capability would alarm rival navies. Their likely response would be to pursue four triple sixteen-inch mounts and then continue increasing armament. Reliable quadruple turrets could therefore accelerate competition in capital-ship design.
