My opinion was anecdotal. But I think it could be argued the entire field of economics has a lot of degrees of freedom - which is why they do not have firm conclusions as to the causes of productivity loss in the article.

It is possible that the drop in productivity growth, if it goes on long enough, will have the effect of closing the gap.
