I see the author's point as quite the opposite:

The processing power of the z is ample, as are its reliability, security, and
economy of operation. But as companies merge and move into new lines
of business and areas of operation, as there are changes in tax laws,
environmental regulations, reporting requirements, and insurance laws;
as operations move to Internet and cashless transactions, management
information systems changes are necessary.
The technology of coding with "glass keypunches" and change management
by 8-digit line numbers is insufficient to the task. And attrition of
programming
talent adds to the need for new techniques.
