As I remarked when this article originally came out last year, there's a certain delicious irony in a hit piece on Rust coming from a company that makes its money writing static analysis tools to try and plug the safety holes in C++. :P
There is irony all around including in the rust communities own positions - relying on jemalloc and llvm while claiming that reliable software cannot be written in C/C++.
Show me where anyone involved in Rust in an official capacity has claimed that "reliable software cannot be written in C/C++"
