Algorithmic idealism holds that reality is not an observer-independent substance but an emergent construct produced by computational rules that select for coherence, sufficiency, and observer-relevant experience, and that personal identity is an informational 'self-state' rather than a materially continuous body. This paper reassesses competing accounts of identity and reality (Parfit's psychological reductionism, quantum Darwinism, Wolfram's Ruliad, and Deutsch-Marletto constructor theory) and argues algorithmic idealism subsumes them by reframing duplication and teletransportation paradoxes as questions about informational continuity rather than material persistence.
This paper explores the intersection of identity, individuality, and reality through competing frameworks, including classical metaphysics, quantum mechanics, and computational theories. Traditional …
