Are we heading towards a real-life portrayal of i-robot where a guy like Will Smith will be all of humanity's savior? well.. too early to judge I reckon.. Having said that, I don't think beating the best Dota players should be a difficult task for a bot.. soon enough we will have bots for all e-games, not only games, all fields where machine language, NLU and AI is involved to whatever extent. And yes, once the bot becomes super intelligent in extracting the right "intents", "entities" and "actions", they could very well over-ride major logic files that could be a real threat to us.
