>I interpreted the argument made in the OP as 'it only becomes an achievement when the computer constrains itself to the boundaries the human has by its nature'

I don't think this is a particularly accurate interpretation considering the author says:

>Now, not to diminish the achievement of the AlphaGo team, what they have done is nothing short of incredible

I think a more charitable interpretation can be found by looking at the closing paragraph which starts with this line:

>So now the interesting question (to me at least) is: How long before a computer will beat the human Go world champion using no more power than the human.
