Second this. Given your couple of bootstrap areas too, either language (or both) will be beneficial. I will say though that in most low level systems that demand absolute performance or that have been around for quite a while it is still mostly C/C++ based. So if you are wanting to break into those areas, then C is going to be the language to know really well.

Other languages are used in both domains, but just wanted to toss that out there to you.
