There are very intelligent people who are weak chess players because they have no experience in chess or because their memory is not good enough to imagine the position 10 plies later correctly. I think that humans have the potential to improve by better training methods. Many years ago people could not use computers to train and today they can do it so it is logical to believe that players of today can be better not because they are more intelligent but because they have more options to train.
