Along the lines of "older coding languages" and the dearth of people with those skills...
There is the story of the COBOL programmer who had a fatal disease but had his body frozen so that he could live on in cryosleep until his disease could be cured. So time passed (but not for him...)
The programmer wakes up in a really advanced looking clinic. There is a doctor and a nurse, but there are a few other folks who are dressed in strange-looking business suits. When the doctor says, "Sir, we have cured you, but these gentlemen have a question for you...."
So the programmer said, "What kind of a question?"
One of the men says, "Our records tell us you can program in COBOL. You see, we have this Y10K problem next year..."
