I wouldn't write those professionals off so easily. People barely knows AlphaGo until now. Once they start learning about AlphaGo's behaviors, they may be able to come out with new tactics. No doubt it will be a collective effort from the Go community, no one can beat the machine alone.

It's true that humans should be allowed a rematch. And all professionals Go players could be playing in concert.

Hell, Google should organize a "AlphaGo against the world" on internet.
