It sounds like you just have a bone to pick here, but I would like to point out that C++ came out of Bell Labs, Java had massive corporate backing including a huge marketing campaign and Go has Google's backing. Each of your examples had huge advantages unrelated to any technical benefit. A closer comparison might be Python, which took a long time to reach its potential, and I see Rust on the same trajectory, with high-profile teams now adopting it, like AWS.
