Yeah Rust is a fairly low level language like C/C++ which should usually give you similar performance once compiled. The reason Rust was made and had become somewhat popular even before LLMs is the language and compiler are very strict. This means it is much harder to introduce things like memory leaks and concurrency issues. However this also means that it is generally more difficult to work in and learn than C due to needing to work within those restrictions especially when trying to get a new project going. However that does mean if you are going to do most of the coding via LLM tools then those tools are bound by the same strict rules and thus less likely to introduce hard to fix/reproduce memory issues.

Yeah the graphene team has done an amazing job of making a privacy/security hardened phone that a regular user would really have to go out of their way to break the security.
