A quote in From Big Data to Deep Data caught my attention:

The real problem of big data is that we are increasingly outsourcing our capacity to sense and think to algorithms programmed into machines

*******************

That is the real benefit and not the problem.   Human beings find it almost impossible to identify meaningful patterns (i.e., sense and develop a perspective) in big data, without the guidance of algorithms, and find the proverbial  needle in the haystack.   Big data is usually great at making lots of little, but rational, decisions in a snap, while the human brain is great at making a big, usually non-rational (not irrational), and infrequent decision – deliberate and slow.   Creativity, imagination and judgment – hallmarks of our brain –  should be augmented with machine (or rational) intelligence, to get the most of big data.  Consequently, in the next two decades, you will see a decrease in the value of the left-brained data scientist (as algorithms get better at rational decisions) and increase in the value of the right-brained creative.
