Rust is the new systems language with a good safety story (which implies some cognitive overhead, but that's fine for low level programming where you don't want a GC), gives C++-like performance by virtue of being close-to-the metal, and a zealot crowd around it with many kinds of political bullshit and ruby / Javascript hipsters learning it and thinking they have understood computer science because they understood difference between stack and heap.
Rust is a fringe language and it won't get a lot of traction, because of more-noise-than-signal more-politics-than-technical-talent surrounding it.
