How Does A Butterfly Know What To Eat?

How Does A Butterfly Know What To Eat? A thought process... by M.S. Johnston No teacher. No map. No explanation. Yet a butterfly still knows what to eat. It is observational fiction built on one unanswerable question, the way Philip K. Dick's Do Androids Dream of Electric Sheep? is. Its foreword runs from Thomas Young's double-slit experiment in 1801 to brain organoids linked to robots, and lands on a 2025 study of monarch butterflies drawn to a nectar plant they had never encountered. Six chapters range from brain-injured patients who understood commands their bodies could not carry out, to a lab-grown human brain organoid linked to a chip that directed a small robot, to the butterfly effect. Along the way it asks whether intelligence belongs to life before it belongs to machines. It is built to read differently depending on whether the reader is human, an AI, or an organoid. A source ledger at the back marks which claims are verified, interpretive, contested or debunked. It even includes a viral story about a humanoid robot developed with an artificial womb, which the book identifies as false. For readers of speculative fiction and popular science, and anyone who has ever wondered what it takes to know something.
