As an account of 2016’s high-stakes battle between a South Korean Go grandmaster and the DeepMind computer program developed for Google by some next-level geeks in London, AlphaGo is genuinely gripping, and comes highly recommended.

As a deeper inquiry into the ramifications of AI, however, Greg Koh’s doc is a little too much in awe of a technology I don’t recall any of us ever asking for. Or, to put it another way, AlphaGo rhapsodically quotes Gary Kasparov—“A good human plus a machine is the best combination”—without considering who built the machine.
