Ask HN: Is OpenAI research the latest wargames? Why not vs. climate change?

OpenAI released their latest algo baselines to the general public yesterday. Their AI is also playing top Dota 2 human teams at The International from later this day. My question as a member of the general public is pretty simple: are these the latest wargames instalments (you know, the Matthew Broderick kool-aid from his 1983 film and so on)? Is it possible to make these AIs play army vs army other than synthetic army vs synthetic army? AIs playing Civilization by Sid Meier is fascinating enough and Youtube is full of demos, but real-life scenarios? At the very least, the weakest links in real plans would be discovered. If so, why not let these latest AIs play vs climate change, for example? Just interested in HNers tech wisdom. Thanks.
