Well, one could put it cynically as Deep has developed a giant "cannon" that can be fired at different very hard but reasonably well defined problems. They've hit go, chess and similar things. Hitting proteins keeps their activity in the limelight. Essentially, DeepMind is demonstrating the value of the money Google paid to purchase it.

The problem is one runs out of reasonably isolated problems with a reasonable metric.
