I know DD is central to a huge amount of computational bridge, and also analysis of human bridge performance. Many people also know that it is extremely limited in true analysis of hand potential scores and contracts and should be used with caution. It concerns me that it seems so integral to much research, analysis and development and that seemingly many people are unaware of the limitations.
I have been testing out many of the products/tools on the market, some better than others in how they handle these limitations. However it does concern me when major products come up with totally ridiculous par scores and contracts that no two partnerships (of any level) would ever reach. What is the point of a piece of software saying that you missed a totally and unfeasible par score.
And it doen't just concern me in Bridge. There are many more "serious" areas of life and work where the kinds of people who do DD analysis are determining critical things in people's lives, how to fly aeroplanes, drive cars, whether people are entitled to government benefits, insurance, trading with our pension funds, predicting health care, involvement in all areas of government policy, healthcare, economics, finance etc. Very dangerous indeed. And please note, I dont necessarily mean the people who build the stuff and know all the limitations; its the less informed people who use hi-tech products/analysis in all areas of our lives who do not understand limitations, who work in organisations where technical limitations are ignored or silenced etc etc
PS I'm not trying to donwplay the seriousness and importance of Bridge
