I agree that it takes a mental leap to go from an imperative language to 
a functional languge, or to a logic-programming / declarative language.

To maintain a Haskell program, one would certainly prefer to hire a 
programmer experienced in functional programming, over one experienced 
only in C, C++ or Ada.

Relying on libraries/packages from the Internet is also a huge 
vulnerability. Not long ago a large part of the world's programs in one 
of these languages (unfortunately I forget which -- it was reported on 
comp.risks) suddenly stopped working because they all depended on 
real-time download of a small library package from a certain repository, 
where the maintainer of that package had quarreled with the repository 
owner/provider and had removed the package. Boom... Fortunately it was a 
very small piece of SW and was easily replaced.

The next step is for a malicious actor to replace some such package with 
malware... the programs which use it will seem to go on working, but may 
not do what they are supposed to do.
