I've dived into Rust a few other times, I just can't find something that makes me want to stick to it. Most of my projects are usually reverse engineering related or web apps I don't have the energy to over engineer in Rust. I prefer simple web frameworks that give you the batteries. When "Django for Rust" becomes a thing I will happily fully embrace Rust.
Maybe worth venturing into the embedded land? There are some pretty cool Rust embedded projects (e.g. embassy) which are sort of best of both worlds. You get to do low level hardware tinkering (which arguably requires a systems programming language) and you get a sort of batteries included environment where you can use all the nice Rust high level features (memory safety, async, etc).
Easier to get started with than OSdev and less gruesome legacy hardware details to study to get stuff done.
Next time I need some lights blinking or actuators actuating I'm gonna do it with Rust and rp2040+.
