Imagine teaching a computer to understand the world like a human. Not just recognizing objects, but understanding context, predicting movement, and making split-second decisions. This was Tesla's challenge in 2017. Their autonomous driving program needed advancement. But they knew something others didn't...

Karpathy's vision was distinct: Instead of relying on multiple sensor types, he believed cars could learn to "see" using primarily cameras. Just like humans don't need radar to drive, cars shouldn't either. This insight would transform the industry forever...

The core of Tesla's vision system was the HydraNet architecture: A neural network that could process data from 8 cameras simultaneously. It could understand depth, detect objects, and make decisions in real time. But there was one massive obstacle standing in their way:
