Typically, AI problems will have a very large space, too large to search or enumerate exhaustively.
But as Go has an even larger search space, it makes sense that DeepMind sees it as a bigger challenge.
Effectively, yes. But I attach no greater philosophical significance to that than to say drilling holes is solved because most people can go buy a nice electric drill foR $30-$40. Flying to the moon is solved, too.
That is incorrect.
