Introduction: Turing, Morphogenesis, and Collective Intelligence
- Alan Turing, known for AI, also studied morphogenesis (pattern formation), seeing a deep connection between intelligence and development. All intelligence is collective intelligence, as every cognitive system is made of parts.
- Developmental biology is crucial: We all start as a single cell and gradually become complex cognitive systems. Embryogenesis is the process of transitioning from “physics” to “mind.” There’s no sharp dividing line.
Key Concepts: Multi-Scale Competency, Goal-Directedness
- Multi-scale competency architecture: Biology uses a nested set of problem-solvers at different levels (cells, tissues, organs, organisms), each with its own goals and competencies.
- Goal-directedness is key: A powerful way to recognize, communicate with, and build unconventional agents is by understanding their goals, even if they are very different from our own. Navigation policies in diverse problem-spaces (not just 3D physical space).
- Cognitive boundary model: A framework for understanding the scaling of cognition based on the size and complexity of goals a system can maintain.
- Morphogenesis as collective intelligence: Cells collectively navigate “morphospace” (the space of possible anatomical forms) using bioelectrical networks as a communication mechanism.
- Practical, empirical predictions: These conceptual ideas lead to testable predictions and have led to discoveries in regenerative medicine and bioengineering.
- Synthetic bioengineering: Life’s competency allows creation of novel bodies/minds, raising ethical considerations.
Single Cells and Basal Cognition
- Single cells (e.g., Lacrymaria, Acetabularia) show impressive spatial and behavioral competencies, challenging the notion of cells as simple building blocks.
- Slime molds (Physarum) demonstrate decision-making, e.g., choosing the larger mass, integrating sensory information through biomechanical sensing (like sonar).
- Morphology and behavior are intertwined, highlighting a transition from solving problems in morphological space to behavioral space during evolution.
Expanding the Concept of “Agent”
- The traditional view of distinct “natural kinds” (human, rat, etc.) needs revision. Evolutionary and developmental processes show continuous transitions.
- Caterpillar metamorphosis: The brain is largely rebuilt, yet memories can persist. This raises questions about memory storage and what it’s like to *become* a different kind of agent.
- Planarian regeneration: Cut worms regrow missing parts, including the brain. Memory (e.g., learned patterns) can be stored *outside* the brain and reimprinted on the new brain.
- Tadpole plasticity: An eye induced on the tail can provide visual input to the brain, even though the eye doesn’t connect directly to the brain. This shows incredible plasticity and adaptability, even in adults.
Multi-Scale Competency Architecture: Nested Problem Solvers
- Nested hierarchy of problem-solvers: Not just whole organisms, but *all* components (cells, tissues, etc.) solve problems in different spaces (transcriptional, anatomical, physiological).
- Competency in unfamiliar spaces: We easily recognize intelligence in 3D behavioral space, but we struggle to recognize it in other spaces (e.g., physiological) due to lack of training data.
- IQ test for recognizing intelligence: Assessing another system’s IQ tests *your* ability to recognize the relevant space and goals.
- TAME Framework, Technological Apprach to Mind Everywhere: a way to evaluate other intelligence whether it be evolution-based or synthesized.
Morphogenesis as Collective Intelligence: A Case Study
- Anatomical order, how collection of cell forms anatomical complexity with fidelity, and the genome not explicitly showing this high level morphology.
- Anatomical compiler (long-term goal): Translating a desired anatomical form into stimuli that guide cells to build it, enabling regenerative medicine and bioengineering.
- Software vs. hardware: We’re good at manipulating molecular hardware (genes, pathways), but far from controlling large-scale structure. We need to understand the “software.”
- Homeostatic process around target morphlogy. Biolelectrity is one mechanism which cells use. Changing the bioelectric setpoint rather than micromanaging the system.
Bioelectricity as an Informational Medium
- The memory usecase of Biolelectricity, for example to remember a set point of anatomical morphology to reach when regrowing in planarians, even remembering the *number* of heads!
- Bioelectrical networks: Cells communicate via ion channels and gap junctions, creating electrical networks that store and process information, similar to (but not identical to) neural networks.
- Neural decoding outside the brain: The same concepts and tools used in neuroscience can be applied to non-neural electrical tissues, offering a “neuroscience outside the brain.”
- “Electric face”: Early frog embryos show a bioelectrical pre-pattern of the future face, long before genes for specific features turn on.
- Optogenetics and gap junction control: Tools to manipulate electrical states and cell communication, allowing functional experiments to test the role of bioelectricity.
- Engineering anatomical structures is more than simply changing genes. By targeting bioelectricity (using sub-routine), organs are regrown (tadpole leg regrowth)
Scaling Cognition and Goal-Directedness
- Scaling of goals: Individual cells have simple goals; cell collectives (through bioelectric networks) pursue larger, more complex goals. Goal size defines level.
- Glioblastoma: Cancer cells disconnect electrically, reverting to a unicellular lifestyle with smaller “self.” Maintaining electrical connections can normalize tumor growth.
- Cognitive “glue”: Bioelectrical networks bind cells together, enabling them to navigate morphospace as a collective.
- Measuring Goal Size to measure intelligence of all kinds. Goal persuit persistance when interrupted defines agenthood. Bending spaces by creating simple constraints from high to low levels.
Xenobots: Engineered by Subtraction
- Evolution pivots problems accross dimensions like behavorial vs morphological.
- Xenobots: Skin cells, isolated from a frog embryo, spontaneously self-organize into novel organisms with emergent behaviors (movement, pile-making). No brain, no neurons.
- Kinematic self-replication: Xenobots build copies of themselves from loose cells – a behavior discovered by AI (Josh Bongard’s lab), and *not* found in frogs.
- Engineered by Subtraction” what cell behaviour appears if freed, so their full behavioural capability comes from both constraints and lack thereof, the “default”.
- Evolution creates machines with broader capabilities for generalized problem solving, than simply for just fulfilling a very narrow set of use-cases.
- The ability to self-assemble shows potential to be agents or problem-solvers in other non-standard evolutionary usecases, posing many societal and safety implications for ethics and decision making.
Other Notes
- Survivorship Bias can easily occur due to our ability to engineer novel constructs which are not constrained by evolutionary history, survival, or adaptability.
- The electrical pattern or set point in an organism may adaptively, be shaped over a wide range of acceptable changes to the ‘settings’, so changes to the organism’s electrical signaling or ion channels can create different results (making for great interface), as cells respond according to the new voltage state.
- Agency Claims are claims on how an organism or collection could act, not the specific low-level mechanism.
- A multi-scale agent (one agent inside a bigger one inside etc…) have a spectrum of interfaces to manipulate to persaude behaviour, with gap junctions helping to meld boundaries to coordinate (the higher scales imposing simple contraints such as by guiding and making easy following down energy grandients) or be interfered with for persuasion by setting constraints.
- The evolution to new intelligence or agent starts as simple single celled goals and then to networking for multiple ones. The networks enable a scaling of not only intelligence but more shared memory between units and prediction capability, along with its homeostatic ability that keeps on growing, and error tolerance through adaptability.
