Without context, this statement means nothing new should ever be done. It's a terrible axiom. Even within the context of this question, if we used this reasoning for the next 500 years we would surely never solve it.
Oh sure, but that's why you have the context. My point is that the time gap between a tool like this becoming technically possible and someone executing it successfully will be incredibly small. So the chances of the current moment in time being in that gap is tiny.
