> So I guess the moral of the story is, if you want to write a greenfield high performance application, Go or Rust should be your choice compared to C++.

I don't see how this generalization follows from the three examples you've cited?

Wishful thinking would be my guess.

Rust in production use tends to be found in circumstances where there is no need for mature tooling, and no expectation of a need to hire experienced coders. Of course there are exceptions.

It is not that hard for C++ developers to pick up Rust. The borrow checker makes explicit safety requirements that exist in C++.

The tooling does need to be more mature but for many projects the pioneer tax paid to improve the tooling may be worth it. Besides, it's not as if C++ dependency management is very mature either — most people build custom tooling for that anyway.
