Retraining becomes a lot harder when the new bar is "become a big data scientist". I mean you mentioned the print workers who were hand setting typeface until quite recently. What did they do after their industry collapsed. Probably a lot of them became taxi drivers or took on other "equivalent" labor centric endeavors. There might not be a fixed amount of work to go around, but there certainly is a fixed amount of vocations that people are willing to pay money for, and that displaced workers can reasonably be expected to move into... And that bell curve does appear to be being squeezed tremendously.
