Fei-Fei Li

She immigrated from China as a teenager, worked in a dry cleaner to survive, and became one of the most important scientists in AI history. When the AI field was obsessed with clever algorithms, she had a different theory: the problem wasn't the code — it was the data. She built ImageNet, a dataset of 14 million labeled images, and it ignited the deep learning revolution. Every image recognition system, every self-driving car, every AI that can "see" traces back to her work. A Grithosian builds the foundation that makes everyone else's breakthroughs possible — and that's the legacy that lasts.
