Technically, if you read the origin story around Golang, it was made to be an alternative to C++. Some departments at Google were going crazy with a myriad of problems involving using C++, so wanted something less troublesome and easier to use.

However, I do agree that it could be argued that Golang has become much more of a Java and C# alternative. Looks like Rust will be shoehorned into C++ and C spaces, but it remains to be seen how successful it will be as an C alternative. Seems like many fans of C are quite resistant or even outright dislike Rust.
