A 4-year-old child is trained on approximately 16,000 waking hours of sensory data (vision, touch, hearing), which through the optic nerve (2 million fibers, each carrying ~1 byte/second) results in about 10^14 bytes of raw data—the same volume as the largest LLMs trained on all publicly available text on the internet.
