"The key point here is our programmers are Googlers, they’re not researchers. They’re typically, fairly young, fresh out of school, probably learned Java, maybe learned C or C++, probably learned Python. They’re not capable of understanding a brilliant language but we want to use them to build good software. So, the language that we give them has to be easy for them to understand and easy to adopt." - Rob Pike Go does not and cannot replace C/C++/Rust family of languages, nor can it replace C# at writing higher-level HPC code (lack of cross-platform SIMD API, zero-cost interop, hardware intrinsics, etc.), something you do to drastically reduce the maintenance effort compared to doing so in C++. And lastly it's still unfortunate it replaces JVM family which goes to show how abysmal the basics of dev UX are in some aspects of it, because it has the most advanced JIT compiler implementations that Go will never be able to compete with.
