For developer/programmer:

This should be posted in the SWYMP. They are in need more for proper programming. 
Fred will post it once they create a Usergroup for Autodesk 
The ‘biggest’ functional language (Haskell) with 130k Github repositories (per the article) is absolutely dwarfed by most other programming languages:
Java: 11,657,394
Javascript: 15,607,544
C: 2,243,601
C++: 2,246,888
C#: 2,247,618
And, as the article says, a lot of functional language features are being added into current languages such as C# and Java. I don’t see them being replaced any time soon.
Just like features added to VB >>>
It still allow “sloppy” programming.
I still see GOTO in code.
DIm all over the place rewriting variables for random results.
For anyone looking for career in programming, functional-programming could be a good direction.
Of course, if you know AS400, you can name your price
