Is there any reason in particular you think a lot of high-level language people are moving to Rust? That is not my impression or experience at all and I struggle to think of any reason to do so besides a large, individual change in career focus. As a higher-level language user myself, I can't think of a single reason I would ever use Rust for anything. Sure, I think it's cool, and it's always good to learn new languages, but in practise it's just not suited to my domain - and I think that goes for the vast majority of us.
I would say golang has scooped off more of the dynamic language types myself, although I also consider it a productivity downgrade and/or cargo cult to mostly be ignored without compelling reason. Which is even more the case with Rust!
