Quoting Ben Affleck

Ben Affleck says he has been interested in computers since he was young, and became more interested as film moved from analog to digital, and that he can write "pretty shitty Python scripts." He notes that visual effects workflows have long included machine learning, and that convolutional neural networks, precursors to what the transformer can do, process tensors to perform edge detection and feature extraction, making it easier to take out the green screen image and replace it with something.
