> My impression is that there's been a lot more people moving to Rust from Python/Ruby/Javascript than from C++ 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!

Fullstack & Wasm. There comes a point in your career where you're dissatisfied with the capabilities of the warm and friendly upper layers of your stack, and you descend into the cold dark waters where things are hard but fast. I used to write primarily in highlevel languages, but if you want to write realy interesting high performance stuff in javascript, WASM+Rust is a really neat tech to use. Similarly, with WebGL/WebGPU you need some familiarity with bare metal programming. I still write a lot of JS, but I regularly drop down to Rust.

I'm migrating everything that's feasible (eg. not stuff where I need Django's ecosystem) from Python to Rust for its combination of a powerful type system that can encode my invariants better than MyPy annotations, sum types, no exceptions, no null, an ecosystem that values "fearless upgrades", PyO3 so my Rust code can be reused in projects that still need Python without me having to get memory-unsafe code right, and not being something as alien as Haskell. Golang specifically has three things that turned me off as a replacement for Python in the early days before I got hooked on what Rust offers: 1. A disgust-inducing level of boilerplate use for things like error-handling and poor support for metaprogramming. 2. A design that not only lacks things like PyO3, but is implicitly hostile to FFI. 3. Git repository URLs as dependency references and "you figure it out" for ensuring they don't go away.
