I too remember punch cards and paper tape (and hand-coding matrix multiplication in PDP-8 assembler, sigh, don't miss that much!). Retired, I no longer need to keep up in order to survive (whew). But I do know that programming languages, styles and concepts have morphed so far since I quit doing it for a living, that I'll never catch up again.
Not sure I'd want to, actually... There's something about the super-formalism and objecty-ness of modern coding practise that for me takes a lot of the fun out of it :-) Seems like 80+ percent of the work nowadays is the structure and packaging and formalising of the code; in my day there was relatively little of that (other than "write some [expletive suppressed] comments, will ya!") and we just got our teeth into the task at hand, right away. Good times.
I could see an interesting discussion thread somewhere, "The Old Programmers' Home" maybe, where we digi-geezers could chat about the antique languages for which we were once valued coders; the languages for which we went to conferences, argued hotly over feature lists, submitted bug reports, contributed to O'Reilly books... My personal language cluster in my working days was Tcl/Tk and SQL, with a tasty sprinkling of gcc and various shells. Now my C language projects mostly happen inside the Arduino IDE :-)
Anyone but me remember VMS, DCL, and -- oh dear -- Datatrieve? Lord, I misspent too much of my youth on that planet!
Ah, the nostalgia... I once got to shake hands with B Kernighan for about 2 seconds. That was kind of a high point.
