This exact fact can actually let you make tons of money, today. There is barely anyone left who knows COBOL, so if you do, you can get one of those many empty job positions out there.
What almost no newbie ever understands, which is especially evident, when they ask, which programming language they should learn first, is the following:
The programming language, in terms of personal knowledge and IT education, is almost never important.
Most of the time, it almost entirely does not matter. When I look back at the time from when I asked which programming language to learn first up to now, then I can only see the biggest difference between compiled and interpreted languages. For example, there is a difference between using Arturo and Nim. Perhaps languages like Smalltalk and Java are a special case, in this specific distinction.
However, I don’t see any really important, from the perspective of programming education, differences between programming languages. If you learn certain general, but important, design patterns and programming concepts, you most likely can implement and use them properly in any popular language.
