This whole rant is uninformed & it seems like the author is completely ignorant of anything happening outside his well.
But I'll bite the Rust rant anyway.
> Where's your SSL?
Right here: https://www.memorysafety.org/blog/rustls-server-perf/
It's an order of magnitude faster than OpenSSL, and almost double the speed of BoringSSL.
> Where's your operating system?
There are lots of OSes written in Rust, but nobody expects them to replace a well-established piece of software like Linux. That's why it's shining in the embedded sector, with stuff such as Tock: https://github.com/tock/tock, or many, many other OSes available today. Oxide Computers uses Rust, Volvo writes a lot of their systems in Rust. I also know a few unnamed MIC companies in Turkey using Rust for their software. Anduril also uses Rust.
Rust also runs the Internet, Cloudflare is primarily Rust and AWS is one of the biggest users of Rust. So many more examples but these are the biggest.
Half my environment is Rust: Helix/Zed my editors, my version control system (jj), my shell (nushell), my Window Manager (niri), the build system I'm working on in Rust to build it all, Firefox which is partially Rust, and I actually enjoy using these greatly, because they're fast, well designed and secure.
Has the author written anything in his life that's not games or toys?

OpenSK
OpenSK is an open-source implementation for security keys written in Rust that supports both FIDO U2F and FIDO2 standards.
-
zenoh
zenoh unifies data in motion, data in-use, data at rest and computations. It carefully blends traditional pub/sub with geo-distributed storages, queries and computations, while retaining a level of time and space efficiency that is well beyond any of the mainstream stacks.
Project mention: Show HN: Decentralized robots (and things) orchestration system | news.ycombinator.com | 2025-01-18Looks very interesting!
How does this compare with Zenoh [1]?
Also, I'm curious why you all included "OS" in the name? Almost every introduction to ROS/ROS2 has to explain that it isn't actually an operating system, and it seems like hyveOS is headed for the same misunderstanding.

Microchip: please hire me to work on the Rust HAL for your ATSAM chips, which I currently volunteer the odd hour or two to help maintain. Between Rust bringing robust modular software in to embedded, and companies like Adafruit pumping out ATSAM boards, there's huge potential in this space.

I don’t know about the job market.
As for use of rust in embedded products, we use it in solokeys and nitokeys (both hardware security keys). We codevelop a framework called Trussed:
