What I really liked about those games so far, and Michael Redmond commentary, is that AlphaGo not only beat Lee Sedol twice, but also Redmond. He is playing the same style as Sedol, he constantly predicts Sedol's moves and he is as surprised and does the same miscalculations as Sedol. He really needs some time to find out when he made a mistake, the same mistake Sedol was eventually doing. This is high class commentary. Even if they have no Computer screen to clear the screen after some variations. He remembers all the stones and immediately clears his own moves, amazing. I'm not sure if a better device would actually help.

Chess grandmasters can often play simultaneously and blindfolded against 20 different opponents (and win all but one or two games). This is nowhere near the extent of Redmond's memory strength. :)
