I have to disagree. Let us take an extreme example - Erlang.
It has very interesting design, which enables you to create highly scalable but quite ineffecient program. There is something in Erlang, that affects _system_ architectures that you can create with it. The notion of scalabiliy - it is how it scales, how fast the performance degrades with number of users, and for some paradigms there is a necessity of support of them in the language. erlang exists only because people wants scalable solutions even though quite slow. From what I said it seems for me that it is obvious that some _languages_ do scale and some do not.
