Eh, I don't think it's actually one or the other. Google has taken on rewriting some more problematic components in rust. See for example:

Binder kernel driver: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin...

Media codecs: https://www.androidauthority.com/android-16-in-process-softw...

This is also happening at Microsoft:

Yeah, there's also a freetype replacement https://github.com/googlefonts/fontations

I think they're trying to avoid rewriting things for no reason though. The things being rewritten tend to have a history of security problems or other issues that would be cause for a rewrite even if it wasn't in Rust.
