I will be holding a presentation for my coworkers about Rust. What should I show about the language that shows its usefulness and value it can bring?

I work with research on robotics and will be holding a presentation about Rust soon. We are using mostly C++ for our work, and I want to show them what the Rust language can add in terms of usefulness for our group.

Currently, I'm thinking about making the presentation a little bit about syntax, a lot about Cargo and the much easier dependency and build process, some concurrency and some about the packages and eco system.

I'd appreciate some input about what I should show off. The more concrete, the better.

Thanks!
