There really aren't any codebases the size of Linux or Windows written in those languages. I'm not saying that there couldn't be, but there isn't currently. There is also a great deal of effort being put into making C++ more robust. When there finally are large codebases written in Rust, it will be apparent that there are still some of the same issues. I think that I agree with you though that there may not be real cases where GC won't work anymore.
