I meant that partly as a joke, I do happen to like Rust though. And in the context of this technical problem, its memory control would make it an attractive possibility (as would C/C++/etc). Lots of context missing as these are merely slides, and I said quite a bit more than what is presented here.
If you're problem is that you're memory bound, using a language that allows precise control over memory allocation and layout is certainly a good idea.
The constant conflict might be annoying but using Rust or even C++ would certainly be a very reasonable choice.
