Many of the articles note that the machines are making moves that humans have never made.  Both in the original, AlphaGo Lee, and in the evolved, AlphaGo Zero, we see games that “no human has ever played.”

So many questions

1. How do we know no human has ever played it?
2. Is the cultural ritual surrounding Go such that as one learns, there is an expectation to adherence of tradition which a human would not diverge from?
3. How do aesthetics play into the success of the machines? (I remember from learning Go decades ago that this mattered, but have read nothing about the aesthetics of the machines’ games. Caveat: I haven’t played in 20 years so what do I know?)
4. Is there any difference than the first principles as given to the machines than those given to humans?
5. Are the games played by the machines admired by the top humans?
6. Is it expected that humans are learning from the machines and that human/human games will now be played differently?
