If you consider all the trade-offs (performance / simplicity / security / etc), and you need to create robust RPC services, whether microservices or outward facing API frontends - Go (to me at least) will be the best choice considering all aspects (C++ may be faster but harder to write/debug in, Java more widely adopted but a nightmare in every other aspect, Python easier but slower and less stable, etc etc).

Think about successful tools use Go - they would have been a nightmare in some aspect in most other languages. Can you imagine Kubernetes in Java? Docker in Python? It shines where it shines for a reason.
