70s and 80s ideas that couldn't be implemented at scale due to the lack of massively parallelized GPU architectures with trillions of transistors to simulate the neurel net layers. It was only in the mid-late 90s that simple handwriting / character recognition techniques were able to be used in somewhat real-time.
