On values, design, and unintended consequences.

Ontology, in philosophy, is the study of being — of what exists, how things are categorized, and the nature of reality itself. An algorithm, in contrast, is a finite set of instructions or rules used by machines to solve problems or make decisions. While one belongs to the realm of metaphysics and the other to mathematics and engineering, the rise of personalized technology has brought them into direct dialogue. In systems driven by personalization — from recommendation engines to news feeds — algorithms are no longer neutral tools. They shape what we see, what we know, and in a very real sense, what exists for us. Through the act of filtering, ranking, and curating, algorithms perform a kind of ontological work: they define what is shown, what is relevant, and what is ignored. In this sense, personalization doesn’t just tailor experience — it constructs a reality. As these systems become more complex and individualized, they raise profound ontological questions: Are we each living in algorithmically constructed worlds? What is real when reality is selectively rendered by code?
