I've seen it unfolding real-time with the famous Lee Sedol / AlphaGo match. On the day before the first match, people were saying how the match would be a joke, as machines would never understand the deep philosophy of go. A few days later, people were saying that it was a matter of calculating stuff very fast and the match was clearly rigged because Lee only had one brain while AlphaGo had thousands of GPUs. (Yes, someone actually said that. Facepalm.)
