What is deepmind going to do once they solve all video games? It seems like they are leveraging the massive economic demand for entertaining simulations of the world. But once they hit the limit of that they will have to make their own simulations.
On another note, even though it was said that DeepMind was APM limited in StarCraft, it did spike to 1500 at some points, which is not doable for a human. So, I'd say that DeepMind hasn't quite got there yet in beating SC2 pros. They could definitely make very interesting single player opponents though. I hope that in the future I can play a strategy game alone and have some interesting AI opponents to play against.
