I'm aware. I note that Firefox is using some Rust code now - so perhaps that will change at some point, for at least one of the common JavaScript implementations, in the not too distant future. I don't imagine we'll see it for the majority within the decade - but who knows, maybe I'll be pleasantly surprised. I have less hope for the widespread adoption of OS kernels written in safer languages - given the general unwillingness to even use C++ there (although plenty of toy/'research' kernels in safer languages do exist.) Although maybe we'll see one within the next century? Perhaps a microkernel for use in containers? Of course, that still leaves bugs in the JITs, compilers, hardware, 'legacy' native interop, unsafe{} blocks, ...
