Have to love our capacity for producing computer models that attempt to predict the future in areas of study where it is quite apparent that any understanding the the relationship between relevant variables is somewhere between crude and non-existent.

It is one thing to have Big Blue beat a grand master in chess, where every variable is known and all that needs to be done is work through a huge number of iterations to determine outcome.  Predicting the climate, the economy and whatever Donald Trump is about to say, is quite a different exercise worth about 5 minutes of attention each year.
