I am not sure whether I agree with the analysis, maybe will take more time to process whether the pixels metric really means efficiency.

However, one interesting point is that the author concludes "Hebrew" and "Gujrati" are the most efficient languages. The cultures to which these languages belong are both stereotyped to be very efficient and pragmatic businesspeople. So maybe they have a general culture which reflects in their day to day activities, even writing.

Arabic [which is the third on the list] also belongs to a people who traditionally have been associated with trade, before they found all the black gold.
