Go isn't good at the system level. I.e. calls to C APIs are expensive, etc.

Wait, I thought Go was designed as a system language.

Go was designed for concurrency (and the docs take care to distinguish that from parallelism), fast compilation, and easy deployment.

Only in the Google sense i.e. "for building big systems… like servers". Not as in "close to your operating system" or "you should write an operating system in it".
