Thanks to Madhur Mangalam for the great conversation on his BeyondPhrenology podcast, discussing my book and the work of Howard Pattee.

Most of molecular biology treats the cell as a computer: a program stored in DNA, executed by proteins.
Pattee saw something else: an architecture of symbols and readers that cannot be collapsed into physics without losing the meaning. (1/2)
5/Prof. @drmichaellevin (@TuftsUniversity) studies how cognition scales from cells to tissues, organisms and synthetic living forms (e.g., his famous xenobots), using bioelectricity to understand pattern regulation, regeneration and diverse intelligence.

Do you love nature? Then you'll love Binghamton! Check out these outdoor spots in upstate New York, all less than a 30-minute drive from #CCS2026!
They're all perfect for hiking 🥾, biking 🚵, camping 🏕️… you name it! Trust us, the fall scenery will take your breath away. 😉🍁
In his new book, Romain Brette pushes back against theories that describe the brain as a “biological computer.” In this excerpt, he challenges equating brain evolution with programming, and the universality of neural network models.

@dpwaters "Behavior and Culture in One Dimension" (2021) is underrated. It helps show how behavior, normativity, and culture cannot be flattened to state transitions without losing the organism-environment unity that makes them intelligible. An excellent intro to biosemiotics!/9

Another crucial distinction is that computation has what Vygotsky called "deliberate semantics," i.e., meaning is assigned from the outside. "X" is whatever we say it is. In living systems meaning emerges through evolution, development, and behavior.
At minimum, computation is a reliable transformation of symbols according to a finite set of rules. That already makes it narrower than "whatever happens in the universe." A rock falls, a cell metabolizes, a storm forms. Not all causation is computation./2

RIP Robert Trivers - the Einstein of evolutionary biology and one the greatest thinkers of our age.
Among other things, Trivers came up with parental investment theory, reciprocal altruism theory, and parent-offspring conflict theory.
Behold the inner channel of the nuclear pore complex in all its messy glory. New high-def microscopy is revealing its intricacies like never before. @yasemin_sap reports: quantamagazine.org/disorder-…
Yes, it's all constrained dynamics: "The reason you can use so many formats to instruct AI is that all of these are really the same thing: attempts to get what’s in one person’s head into someone else’s actions."

If you exclude robotics from the question, and only focus on current AI models, then the point might be made. But robotics is precisely where Moravec's paradox hits the hardest. Some of the last people that will (if ever) lose their jobs to robots are farm field workers. That's were the paradox really needs exploring.
