The Forward Forward Algorithm : future of AI ?

Geoffrey Hinton was one of the scientists that devised backpropagation, the method that permits deep neural network training, in the 1980s. And it was his team who released ImageNet Classification using Deep Convolutional Neural Networks ten years ago, showing the first convolutional neural network to considerably outperform state-of-the-art ImageNet database results. In his recently written paper, he proposes a new method which he calls "The Forward Forward Algorithm". Deep Neural Networks have made huge progress through the years and backpropagation has been the norm. These networks which were inspired by our brain backpropagate an error gradient to tune all("could be in billions") of its parameters or weights.
