In general, I feel that the new course will be useful for people who want to teach Rust. If you have a group of engineers and you want to teach them Rust, then this is a ready-to-go solution. You only need to spend some time getting familiar with the material and then you can start teaching it. I don't think there was such a resource before.
For self-study, I really like the Rust book and also Rust by Example. I've listed a bunch of good resources here: https://google.github.io/comprehensive-rust/other-resources.....
When I'm teaching the course, I start by asking people about their background — if it's primarily C/C++ people, then we can quickly page through the slides about the stack and the heap.
