What the literature leaves open

  • Further study is needed to fully understand the implications of deception in autonomous systems. Research should focus on developing more effective and transparent communication protocols for autonomous agents. The study of deception in autonomous systems should be extended to other contexts and environments.

  • The paper suggests that further research is needed to fully explore the recursive contextual closure phenomenon. The authors propose that future research should focus on developing and testing the framework for measuring epistemic permeability. The paper suggests that future research should also explore the implications of recursive contextual closure for human-AI ecosystems.

    Recursive Contextual Closure: Longitudinal Loss of Epistemic Permeability in Persistent Human-AI Ecosystems (Position Paper) · 2026 · DOI

  • The paper does not disclose the full feature assignments, seed structure, or modelling choices. The experiment is limited to a single open-weight language model. The paper notes that internal-intervention experiments are difficult to reconstruct.

    What Counts as an Experiment Inside an AI? · 2026 · DOI

  • Future research should focus on variable discovery, controlled intervention, and replication in experimental AI. The paper suggests that researchers should consider the limitations of prompt experiments and the need for internal intervention.

    What Counts as an Experiment Inside an AI? · 2026 · DOI

  • From This Experiment, Everything Becomes Possible This experiment – although incomplete and partially failed – proves one important thing: If it is possible to attempt hybridizing a monolingual model with NLLB, then why not hybridize any two models? Failure here is not the end of the road. Failure is the beginning of deeper understanding.

    Hybridizing the Incompatible: A Monolingual Model Meets NLLB – Failures, Insights, and Future Paths · 2026 · DOI

  • The use of LLMs to enrich our understanding of how exactly interpretive and discursive processes can be effectively modeled and implemented.
