But that's the thing where you are wrong. They clearly state they don't want C developers to learn Rust. In the particular video posted he was saying "I want you to explain to me how this particular API works so that I can do it"
The concerns about who fixes what on a merge when the C code breaks Rust code are valid, but that's easily fixed by gathering with the Rust developers, explaining the changes and letting them fix it.
That's the journalists' fault. They have no business going through studies like this, that are not meant for them to make conclusions.
Just stop spreading this bs, and stop reading news like these. Believe what accredited sources tell you, like your doctor or other professionals
