alt Hacker NewsOnly because Rust is a source only language for distribution.
One business domain that Rust currently doesn't have an answer for, is selling commercial SDKs with binary libraries, which is exactly the kind of customers that get pissed off when C and C++ compilers break ABIs.
Microsoft mentions this in the adoption issues they are having with Rust, see talks from Victor Ciura, and while they can work around this with DLLs and COM/WinRT, it isn't optimal, after all Rust's safety gets reduced to the OS ABI for DLLs and COM.

Rust allows binary libraries with a C ABI. Having safety within any given module is still a big deal, and it's hard to guarantee safety across dynamic modules when the code that's actually loaded can be overridden by a separately-built version.
I'm not expecting to convince you of this position, but I find it to be a feature, not a bug, that Rust is inherently hostile to companies whose business models rely on tossing closed-source proprietary blobs over the wall. I'm fairly certain that Andrew Kelley would say the same thing about Zig. Give me the source or GTFO.
