"I ended up thinking every possible error" sounds a bit bold.. Ok the more low-level a language is the more you will have control on everything, but hey, Go is not ASM and you will still risk making mistakes. Even having just one error you didn't think of, then when it presents itself and you're coming back to the code after months, I'm not sure which language, Ruby or Go, will be more pleasant on you..
