> Modern C++ pretty much solves the safety issues.

The statistics from projects that have adopted Rust and measured the effect say otherwise. See https://security.googleblog.com/2025/11/rust-in-android-move... for example.

This article is not really specifying if Rust is compared against "Modern C++" or "Old School C++". The only thing we can assume is that at least part of it is "Google C++".

Maybe we would see similar effects adopting Modern C++. Maybe not. The article doesn't tell us.
