I believe that there is a good reason.

Rust is currently in the process of trying to eat some of C++'s cake (as well as that of Java, C# or Go). The usual response from C++ (Java, etc.) devotees is that Rust hasn't been tried on large projects so it cannot be compared. Which absolutely makes sense.

Each large scale project that demonstrates that Rust can be used successfully in a domain where C++ (Java, etc.) traditionally rules is a step forward for the Rust community.

Also, as with every language, there is a hype period. We're currently in the Rust honeymoon. My personal honeymoon has stopped a while ago, but Rust remains my favorite language for the foreseeable future.

People overreact to hype and anti-hype. Rust is already a useful tool and has momentum. But it's not trivial to get into and it won't replace C++ codebases overnight either.

Based on historical data, a good lower bound for its future could be Ruby. According to TIOBE, Rust overtook Ruby in popularity, while Ruby has maintained roughly the same popularity for years. At worst, I expect Ruby to stay about as relevant as Ruby on Rails. But it doesn't look that way...
