Certainly you misunderstood: more people pick up C++ for production use every week than the total employed today coding Rust. That will be true next year, too. More are employed coding Ada than Rust. More code Erlang than Rust. More code Forth than Rust. Rust is not "used widely" by any defensible definition.

It still seems possible that Rust could, someday, come to be used widely, beyond the HN echo chamber, but only with serious action. Wishful thinking has always reliably failed to drive mainstream language adoption.
