The talk had a diagram, most components on it were in Rust, and the plan is to use more and more moving forward. Even critical stuff.
However, from plans to actual usage takes years; specially for completely new projects using new languages, compilers, libraries, etc. in safety-critical stuff, that takes months just to validate.
Stating anything else is just either lying (marketing) or ignorance. Please do not do a disservice to your language by creating vacuous hype.
