As a full time C++ dev I think the biggest argument is missing in this article: The consistent build and package management ecosystem.

With rust/cargo _it_ _just_ _works_. So many hours each month are wasted because of weird linker errors between linker targets, that cannot find a definition of a struct, dealing with broken external dependencies (yes I use vcpkg for that, still happens) and different build tools. I did get better the last few years, but still miles away from what Rust offers.
