I recently decided to leave go and back to c++ for a microservice project, with the new coroutine and async in modern c++, I failed to see anything Go can that c++ can not do, plus the latter has no GC and is just more performant. I will stick to c++ for other future projects. tried Rust for a few times, finally gave up due to the learning curve and still young ecosystem, it's hard to learn multiple languages and become good with them, I will pinpoint on c++ for other new projects as it seems can do all I wanted.
