> Go was originally envisioned as a systems programming language.
Already with the release of Go 1 it was quite clear that Go has its best fit as a Server language. I don't think the usage of a language can really be planned. But looking at the previous works of the language authors, it's clear that they worked on solutions for distributed systems.
Also I think like 10 years ago people would have written stuff in C++ that today nobody would even remotely consider writing in it.
