there is no question that C is more complicated to learn than Go, but Go gives you a lot of teh performance (about 90%, and the main limitations are that Go is not so good at parallelism compared to using pthreads)

i'd also suggest trying C because it's pretty good for writing simple mathematical algorithms with, but the implicit types get messy, and personally one of the things i hate about Go is the fact that the `int` type is 32 bit on 32 bit hardware, and you see this sometimes in code, people using explicit int64 (signed) in a lot of places even though in practice, almost nobody puts serious servers on 32 bit processors
