I mean the choice isn't literally arbitrary but it matters a lot less than the ecosystem and you can't really make a wrong choice as .NET, JS, PHP, Java, Ruby, Python, Go, $ReasonablyPopularLang are all plenty productive.

Sure, but there are legitimate criticisms around types, complexity, security, maintainability, scalability and performance where the language choice can matter. Certainly when the project gets large.

[mtnGoat]

those concerns prevail in every large project i've seen, regardless of language.

I think skill and knowledge of the coders is vastly more important then the language choice... you can write insecure, slow code in any language.
