So this is particularly untrue for the game of Go. The game is in fact uniquely difficult as there are more board combinations than there are atoms in the universe. It is effectively impossible to brute force it as we did with chess, so a new approach had to be created. Until Deep Mind completes the task, even AI experts were genuinely unsure if we would ever solve it.

It really is a new advancement to be able to solve Go. It is not just a logical extension of work we had already done or something that would be automatically solved by faster computers. We had to invent a new approach.
