The problem is that while the PCs are getting faster, I'm slowing down.

One vivid memory I have of the S/360 F-level assembler is that while the
macro language was very rich, macros could take a very long time to
evaluate.  Some of the "system" macros were real doozies.

Of course, none of that compares to the card-only systems without mass
