https://www.youtube.com/watch?v=mRzxTzKIsp8Can be teased into a real world variant of the partial derivative of a function with respect to a direction, via additions which stack to dot product. And so if the downstream can accumulate the results of these partial derivatives and only send back the ones that passed both downstream and upstream calculations, you've got yourself a non-living thing in the universe that can create the protoguts of the living thing, an organism that can figure out how to creep up and get both the reptitive production environment and the flow calculation and return-to-sender redirect all into a hull.
This took over 2 billion years to happen on Earth, assuming it came from Earth. It may have come from outer spaaaaaaace.
DNA, like the hull, is also very late stage life.
The first life only had 2 mechanisms: reptitive production machine miniaturized to the atomic, and the flow selection mechanism a simulation of environmental pressures brought into genetic selection pressures, the things you see when you put your balls and eggs under an electron microscope:
