Personally, I think it is incomprehensible. After all, the program is just a program. Although it is artificial intelligence on the surface, let's put the mobile phone in ancient times. The ancients looked at the mobile phone playing music and said, "Can this thing really sing?" This question is the same as the title. Alpha dog only surpasses the speed of human thinking in program operation, but it does not prove that an artificial intelligence can really understand Go. Understanding belongs only to human beings. Just like thinking, thinking is exclusive to people. No matter how powerful the alpha dog is, it is artificial, and it is artificially endowed with computing power. In its so-called understanding, it is just a lot of cloud data.
