Programming languages never die, they just fade into obscurity. But some don’t even do that. Which older language are you still using the most?
Source: Which ‘ancient’ programming language do you use the most?
I am still using Cobol for my day job. It may be “ancient” but there are too many systems written in Cobol for it to ever “die”.
Also, to redesign systems written in Cobol to other “modern” languages or technologies.
