Responding to Rich Sutton's bitter lesson, the author argues a corresponding sweet lesson holds: ML problems fall into two camps. For tasks where you have absolutely no idea how to write the algorithm (e.g. language modeling), the bitter lesson applies—scale wins. For problems where you roughly know the nature of the computation, the sweet lesson says you can restrict how the network operates and prune the search space of possible solutions for better performance.
