Maybe you haven't been paying much attention in this space. Google found empirically that error density in _unsafe_ Rust is still much lower than in C/C++. And only a small portion of code is unsafe. So per LOC Rust has orders of magnitudes fewer errors than C/C++ in real world Android development. And these are not small sample sizes. By now more code is being written in Rust than C++ at Google:

But don't take my word for it, you can hear about the benefits of Rust directly from GKH:

There really isn't a good faith argument here. You can make mistakes in Rust? No one denies that. There is more C code so of course there are more mistakes in C code than in Rust? Complete red herring.
