Summary

Explores Maximum Theoretical Agent (MTA)—opposite extreme from MVA. Agency spectrum from minimal (limited predictions, restricted influence) to maximal (comprehensive awareness of all timelines, complete control over branching).

Theoretical Foundations: Solomonoff Induction (predicting via algorithmic simplicity) + AIXI agent (Hutter’s optimal decision-maker using Solomonoff + reinforcement learning).

AIXI Demon Thought Experiment: Laplace’s Demon analogue for QBU. In “Quantum Garden” of future choices, AIXI Demon sees all branches with precise probabilities, perfect prediction of divergence/convergence including interference, optimal action selection steering timelines toward goals.

Example: Job decision abroad vs home—demon visualizes all timelines labeled by fulfillment/relationships/success, instantly determines optimal choice.

Implications: Clarifies agency spectrum, computational limits (MTA practically unattainable), ethical questions about responsibility/determinism, AI alignment insights (risks/benefits of powerful predictive systems).
