and I am sure that he is right about how most of IBM's mainframe
customers view this issue.

What also needs to be understood is that these views are very odd ones
indeed.  Applications do not begin to stink so soon as fresh fish, but
they do not age gracefully.

As they age maintenance costs for them rise sharply, and this has a
peculiarly unfortunate consequence.  Force-majeure maintenance, made
necessary by changed regulatory and reporting requirements, absorbs
all of the available resources.

Not much is left for new or enhanced features, and in the upshot the
users of these old applications come to view the IT departments
responsible for them as unresponsive to their needs.

I have never encountered an application more than ten years old that
did not have a bad, musty smell; and the crackpot realism that avoids
revisiting them is killing the mainframe.   z/OS is a superb vehicle;
the hardware on which it is executed is many orders of magnitude more
reliable than anyone's PCs; the uses being made of these facilities
are mediocre or worse.
