I agree that writing in a fast, compiled, statically typed language is not necessarily premature optimization. It is my first choice for a new project in the absence of any other mitigating factors.
There are often mitigating factors, though.
And switching from an existing language to use a new one that is possibly more optimized carries costs that have to be considered. If the new implementation shaves a few percent off some time or other resource scale, and the sum of that savings over the life of the program is more than the cost to do development and maintenance it's worth it. But that often isn't the case.
