I intentionally said most, since, obviously there are serious domain-specific languages. But stating that Go is designed for large code bases, creates a false dichotomy.

Go has the advantage of being designed for the kind of thing Google does - massive concurrency.

So, claims the C fan since there's GCD, so claims the Erlang/Scala fan since it has actors, so claims the Haskell fan since it has green threads, STM, and purity.

Also, is Google interested in massive concurrency or parallelism?

It's also like C, which make it easier to find good programmers who are confortable with it. Actually, you'd be hard pressed to find good programmers who are uncomfortable with a language that's nearly C.

That's a good point. But as a result it provides only a marginally better type system, at the cost of performance compared to C. Why not make it a lot better than C, with the same performance?
