I was sceptical at first but after watching MaNa story video [0] - not anymore. Starcraft2 is a very complex game, but I’ve been able to crush best blizzard AI after a week playing - yes its that weak. Seeing AlphaStar strategy, from simple correct building placement to micro decision making is so much more inspiring. And it was achieved by deep reinforcement learning - never seen a more unstable and unpredictable algorithms in my machine learning career - even in fully observable environments. What DeepMind did - achieving THAT level of play, even if AlphaStar can see the whole map and micro 3 groups of units at once - is incredible.
