This is the most basic question in the research program. We need to determine what allows interaction histories to become stable, reusable semantic structure.
- Which architectural biases are necessary?
- Should objectness be built in, introduced as a weak prior, or emerge entirely from controllability and persistence?
- How do relations, local dynamics, and causal variables form?
- Is prediction value-equivalence sufficient to produce stable concepts?
- How can a system distinguish a useful feature from a novel concept?
- Must abstractions become discrete, or can a continuous manifold support language-like structure?
Criterion. An abstraction should support intervention, composition, transfer, and reduced exploration steps on new tasks.
