Hard Problem of Plant Cognition

The debate over whether plants' complex adaptive behaviors—like root networks solving resource distribution puzzles or leaves optimizing sunlight capture—count as a form of "thinking." The hard problem here is: If they have no neurons, where and what is the "cognitive workspace"? How do we recognize cognition in a system so alien, operating on a timescale of hours or days, without a central processor? It's the challenge of defining cognition so it isn't just "brain-based information processing," potentially forcing us to see intelligence in silent, slow-motion biological algorithms.

Example: "The vine grew a perfect path through the lattice, avoiding painted (toxic) sections. The hard problem of plant cognition: Was that a cognitive choice, a simple chemical tropism, or a beautiful, mindless computation? And if there's no difference in outcome, does the 'mind' part even matter?"
