I mean, the advantages of C++ are complexity management and the downside is its abstractness which is what Linus' argument was about (It is a behemoth compared to C therefore easy to make mistakes). Rust might prove to be a possible candidate because it can help with safety. This is a different rationale than what the argument for C++ was about, so we cannot say. The bigger problem I see is how premature the Rust eco-system and understanding is. It needs to go quite a long way people people start believing in it and before the language is well understood by more than a niche group of people who learn it just out of interest.
