If you've read any of the professional commentary on the play style of AlphaGo, it's nothing like a human. The crux of it's ability is to be able to calculate the status of the board to the fraction of a point and take moves that advance the position by fractions of a point. Humans on the other hand tend to make moves that will swing the board by several points. As a result Alphago will never play a kami no itte, unlike Sedol who did in his single win against the computer. In other words, AlphaGo is better at microagression and the humans are still better at "the perfect play". Unfortunately for humans, it takes the absolute perfect play to beat microagression.
