I broadly agree, though I think you might be under-counting the degree to which accumulated ecosystem value drives this phenomenon, especially amongst a group of languages not known for strong mutual interoperability. Java is fucking fast, I imagine Cliff Click would like a word with someone arguing golang outperforms a well-tuned JVM. But the language isn’t aging the best and interop with non-JVM languages is, also not the best. golang seems pretty optimized for polyglot SOA-type setups where a comparatively modest amount of existing code compared to say C++ isn’t a real drawback because you’re hitting that stuff over the network anyways. Rust is probably the better language in C++ niches at this point when you don’t have a big C++ ecosystem investment and can do a more “greenfield”-type project. That can become a holy war and I’ll leave my position at: “there are good reasons to choose both”.
