Yes, I didn't mention that but they have a rotating schedule of some of the most elite programmers you have ever heard. I will also say that array programming is very seductive if you have the "puzzle solving" mentality that a lot of us have. It seems so elegant. I have never found a legitimate use for it in my paying work, but I am captivated by it privately.
I don't mean that the languages are not legitimate, mostly what would be acceptable to either management or a client. Also, I feel that setting someone up with code that they might have to maintain if I leave should be easy for them to handle and J, APL, or K would require them finding a rare developer.
Both are reasonable concerns. If you were running your own company the calculus might change though. Or not but I’d say it certainly could. Similarly for code which is not client facing.
