Well, yes, of course. Rust is not made by Apple, MS or Google who can just make it new "official" language on their platform and force adoption. Also, by its very nature (low-level-ish language without GC) it cannot have Python-level adoption in modern software development ecosystem.

Why would you want Rust to target lowest-common-denominator developers and become new VB or php? All it needs is enough momentum to become self-sufficient, which seems to be actually happening now with Rust Foundation and news of its usage in some major companies that can set the trends for whole industry (Amazon, Google, etc.).
