Writing extensions in c/c++ largely negates all stated benefits of using Python in the first place, and I'm proficient in all three languages. Further, mypy is hopeful, but it's not quite there yet (lots of holes and bugs--notably no support for recursive types). Lastly multiprocessing for parallelism is a poor man's solution, and far from what I've become accustomed to in Go, Rust, etc. Python is a nice language and it pays my bills, but Go beats it at many of its own purported strengths, in my opinion.
