Also I've found that teams that focus on easily understandable languages (Python I think is the best with its "executable pseudocode" syntax) are those that are placing value on teamwork rather than individual flexing.
I - er.. okay.
I have also seen teams using languages traditionally considered "easy-to-understand" use various forms of meta-programming to customize the code and make it even more easy to understand... eventually reaching the point where nobody except the experts of this specific sublanguage could understand it.
I have seen teams using languages considered hard-to-understand being obsessed with documentation and communication – and others who don't care at all.
I've come to the conclusion that it's a teams thing, much more than a language thing.
