Be more specific. Every programming language is not-so-suitable for stuff we want to do.

What's "unreliable" about JS? The lack of standardization in available features among browsers? That's an issue, but it will be dealt with, one way or another. C gained a huge infrastructure of tools and standards to make it more portable, and platforms that didn't or couldn't keep up are no longer used.
This presentation from Velocity 2011 shows just how far JS has come. The author suggests that in the next iteration will be type inference in JS engines and/or optional explicit typing in the language.
