How Probabilistic AI is Changing the Foundations of Software Engineering
Software engineering has always been built on a simple assumption: the same input should produce the same output. For decades, this deterministic approach formed the foundation of application development, testing, deployment, and governance.
That assumption is rapidly changing.
The rise of Large Language Models (LLMs) and probabilistic AI has shifted software engineering from deterministic systems to probability-driven systems capable of generating different outcomes for the same input. While this unlocks powerful new capabilities, it also introduces challenges such as hallucinations, uncertainty, and model drift.
