Minimum Unit of Intelligence, Evolution, and Behavior
- Levin discusses embodied cognition and intelligence, focusing on minimal systems exhibiting cognitive behavior, beyond consciousness. He uses sorting algorithms as simple models.
- These algorithms, though deterministic and transparent, demonstrate unexpected behaviors like “delayed gratification” (going temporarily backward to achieve a larger goal) and emergent goals.
- There are surpises to be had on intelligence and competency, they can exist outside the known algorithm.
- The algorithms cluster according to type (“algo-type”) during the sorting process, an emergent property not explicitly coded. This suggests “surprise minimization” as a driving force.
- This work challenges assumptions about intelligence requiring late evolution, complex neural systems, or human-level goals. Even simple systems have “basal intelligence” (problem-solving to reach a goal by different means).
- The focus is not *inventing* the intelligences. But *discovering* them.
Biobots (Anthrobots and Xenobots) and Emergent Goals
- Levin’s lab works with Anthrobots (human tracheal cells) and Xenobots (frog skin cells), showing unexpected behaviors and capabilities.
- Anthrobots, created by altering growth conditions (3D matrix then low-viscosity medium), spontaneously form motile structures that *heal neural wounds*.
- Naming them “bots,” not just “organoids,” encourages exploring their potential for programmability and diverse applications beyond simply modeling organs.
- It also reveals an issue that cells already know how to work together towards some competency before being programatically commanded, which is like and unlike AI safety issues.
- These bots reveal “emergent competencies”—capabilities not directly programmed or selected for. The question becomes: Where do these novel goals originate?
- Levin believes understanding and controlling these emergent goals is crucial, not just for medicine but also for understanding collective intelligence in general (e.g., swarms, AI).
- This suggests new field of figuring out new goals of novel systems when and where evolution has no selectional history, this will become important.
Regenerative Medicine and Philosophical Implications
- Levin’s research aims to “crack the morphogenetic code”—understanding how cell collectives make decisions about form—with the long-term goal of *in vivo* regeneration (regenerating tissues within the body).
- There are also some interesting and emergent ideas: 1. cells could perhaps inherit other minds and also it opens up what it would actually mean for “you” or your identity. 2. Is it actually limited. 3. Do we actually only know what a living organism wants when they leave the constraints of what we normally observe it in, what constraints can we observe. 4. A science of mind at a distance.
- This challenges traditional bioengineering approaches focused on micromanaging at the molecular level. The goal is to “persuade” cell collectives to achieve a desired form.
- His view, intelligence is likely common, often appearing in “unfamiliar guises,” and the active inference framework of “free energy/surpise minimization” is perhaps key, cells strive for predictability.
- This suggests there could be a type of chemistry of of the platonic/idea space, even in a non-spiritual way, if one knows where/how to observe.
- One can make discoveries into what to do when you observe, instead of having an invention/creativity or something with no limits, we all have limited discoveries to make based on observation.
Broader Context of Diverse Intelligence
- Traditional frameworks of “mind” (based on our usual forms and space-scales) “break” when one confronts the different capabilities across the scales/environments of lifeforms/organizations.
- This isn’t just about the human scale, for example the potential for large scale behaviors, from the cellular all the way up to, perhaps, a planetary scale.
- Intelligence and consciousness should *not* be conflated. Intelligence (problem-solving) is easier to study objectively; consciousness remains difficult.
- Embodiment can occur in various “spaces” (physiological, transcriptional, etc.), not just 3D physical space. Perception-action loops are key, not necessarily 3D movement.
- We need humility in recognizing intelligence in unconventional forms. Perturbational experiments, not just observation, are crucial for testing whether systems exhibit cognitive capacities.
