Episode notes
Purpose Produces Mechanoidal Behavior
- When a system is adapted for a simple overall purpose, its underlying computational irreducibility gets constrained into pockets of reducibility.
- Stephen Wolfram calls the resulting locally mechanism-like behavior "mechanoidal" and sees it as a generic signature of purposeful systems.
Rule Ensembles Replace Microstate Ensembles
- Replace ensembles of microstates with an ensemble of rules: the Rulial (Rulial) ensemble concentrates rules that achieve a purpose.
- For computationally simple fitness criteria, the Rulial ensemble shows universal, predictable properties.
Simple Fitness Enables Evolution
- Biological fitness functions are plausibly computationally simple, which makes evolution tractable.
- Wolfram argues this simplicity is necessary for evolution to find solutions amid computational irreducibility.
