Kind of a weird headline, the vision-based RL this article dubs 'powerful AI' could already easily be trained on a single (pretty expensive) computer. They say as much in terms of the speed ups they provide: "Using a single machine equipped with a 36-core CPU and one GPU, the researchers were able to process roughly 140,000 frames per second while training on Atari videogames and Doom, or double the next best approach. On the 3D training environment DeepMind Lab, they clocked 40,000 frames per second—about 15 percent better than second place." So, not massive this-is-now-doable speedup.
