Michael Levin studies problem solving in systems with no nervous system. Cells coordinate through bioelectric signalling to build and repair anatomical structures, and they pursue those targets adaptively, taking different routes when the usual one is blocked. That is goal directedness in tissue, and it forces a question about where cognition starts.

His cognitive light cone framework makes the question tractable. Every agent has a boundary on the goals it can represent and pursue, in space and in time. A cell’s is small, a human’s is large, and the framework treats the difference as a continuum rather than a line between minds and non-minds. Nothing in it privileges neurons.

For artificial systems this cuts against both camps. It undermines the assumption that brains are the relevant reference class, which weakens biological naturalism. It also undermines the assumption that scale and capability are what matter, since a system can be enormously capable with a very small light cone. What Levin’s work suggests is that the right question is not whether a system is conscious but what the boundary of its goals is, and that this is measurable.
