The Proof Must Go On: Formal Methods in the Theater of Secure Software Development of the Future

Abstract

Formal Methods (FM) will not arrive with fanfare. It will spread quietly, not as a revolution, but as a patch: reviewed, merged, and dismissed. In the coming century, the decades-old practice of simply testing code will collapse under the weight of cyberattacks and development complexity.

It is succeeded by a slower, more methodical approach as FM becomes infrastructure. Verified C libraries thread their way into the systems that run the internet. Model checkers embed themselves in CI pipelines. Modern type systems reach the masses. AI and IO remain stubbornly unverifiable and insecure, forcing industry to work towards a deeper form of trust. Meanwhile, a generation of developers learns to write specifications not as a niche academic exercise, but as a matter of professional survival.

This paper tells a fictional, yet historically-grounded, story of how formal verification goes from lofty fantasy to invisible standard throughout the century, and how, without anyone noticing, the proof goes on.
