Reality Check
Despite 60 years of hard work no AGI
Funding situation is dire Reputation is poor Bad news: things seem to
continue along the same trajectory

Can convergence happen?
AGI researchers diverge on disparate trajectories
No consensus on what AGI really is Claim: we need a unified view of
overarching goals Proposition: an initial framework to
facilitate consensus of short-term research focus

The case for AGI Axioms
Def: core functional attributes without which an AGI system cannot be considered one
Necessary but not sufficient set Advantages
Help unify terminology Promote an eventual roadmap Discard non-AGI propositions

Axiom #1: Observability
AGI system must have the ability to continuously receive observations from its environment
Appears obvious, but critical The particular nature of observations
irrelevant May be partial with respect to
environment state

Axiom #2: Actuation Capability
Ability to impact environment in some desired manner
Without this – no control loop – no AGI
“Thinking” by itself is insufficient Implies physical actuators (or virtual
ones)

Axiom #3: Process High-Dimensional Data
Mammal brains concurrently exposed to high-dimensional sensory information
A system with limitation on that is not AGI
Typically multi-modal sensory information
Sensory data fusion will take place

Axiom #4: Capturing Spatiotemporal Dependencies
Core human brain capability Representing wide time scale is
critical Anticipating events as
consequence of other events Tied to pattern recognition

Axiom #5: Utility Function
Existence of functional goal Drives action selection Not necessary reinforcement
learning like Intrinsic feedback in addition to
external Credit assignment problem –
“strategic thinking”

Avoiding the 10 IQ Fallacy
AGI is hard to demonstrate on small-scale problems
Narrow “AI” can always step in (sometimes do better)
Axioms should reflect “true” AGI attributes
