How does HR fit into an artificially intelligent future?

The reason for the continued existence of HR is in the name: humans are fickle and complicated characters who don't fit into nicely defined boxes, unlike computers. As far as we might get with AI and machine learning, there is no substitute for emotional intelligence, and many of an HR manager's processes are too nuanced to be reduced to a binary solution. However, machine learning will significantly increase the efficiency of the HR manager. To illustrate the progress of machine learning, Facebook can now define someone's personality better than their spouse, based on just 300 'likes'. While an HR manager would not be advised to use this method, an unstructured machine learning application could quickly build up a profile of strengths and weaknesses of employees.
