Maryanne Wolf

The human brain contains no gene for reading. No neural circuit evolved for literacy. When Maryanne Wolf began her decades of research at Tufts and later at UCLA, she confronted the foundational fact that makes her work so consequential for the AI age: reading is not natural but constructed, not innate but built through years of sustained, effortful practice that physically restructures the brain. Her central contribution—the concept of the reading circuit—names the recruited and reorganized neural architecture that literacy requires: visual cortex, auditory processing, language comprehension, memory, and motor planning all coordinated into a new ensemble that performs a task none of them were individually designed to perform. The circuit is not metaphorical; it is visible on neuroimaging scans, and it supports the cognitive capacities that Wolf identifies as the irreplaceable human contribution to the age of large language models: sustained attention, inferential reasoning, critical analysis, empathic imagination, and the cognitive patience to sit with hard problems until genuine understanding emerges. What AI can provide is information; what
