Which defeats the purpose of having it in rust.

That is incorrect.

Identifying where code is unsafe, is a qualitative improvement. Not guaranteed to be complete, but more complete than a language that does not focus on that concern. Moving forward, the benefits of Rust compound. The concern about AI is orthogonal to the concern about moving to Rust.

Now there are 2 versions[1] that can be instrumented, regardless of the misgivings about AI.
