If you’re still shipping load‑bearing code in C, C++, Python, or vanilla JavaScript in 2025, you’re gambling with house money and calling it “experience.”
As systems scale, untyped or foot‑gun‑heavy languages don’t just get harder to work with—they hit a complexity cliff. Every new feature is another chance for a runtime type error or a memory bug to land in prod. Now layer LLM‑generated glue code on top of that. More code, more surface area, less anyone truly understands. In that world, “we’ll catch it in tests” is wishful thinking, not a strategy.
We don’t live in 1998 anymore. We have languages that:
- Make whole classes of bugs unrepresentable (Rust, TypeScript)
- Give you memory safety and concurrency sanity by default (Rust, Go)
- Provide static structure that both humans and LLMs can lean on as guardrails, not red tape
At this point, choosing C/C++ for safety‑critical paths, or dynamic languages for the core of a large system, isn’t just “old school.” It’s negligence with better marketing.
Use Rust, Go, or TypeScript for anything that actually matters. Use Python/JS at the edges, for scripts and prototypes.
For production, load‑bearing paths in 2025 and beyond, anything else is you saying, out loud:
“I’m okay with avoidable runtime failures and undefined behavior in my critical systems.”
Are you?

Nonsense. If your code has reached the point of unmaintainable complexity, then blame the author, not the language.
Not an embedded dev. What’s the Rust situation in the embedded world? Is it ever used?
Bindings have been getting added to the Linux kernel so drivers can theoretically be written in Rust
Android has moved its IPC mechanism, Binder, over to Rust
I know that some people have managed to get it working but I have yet to see it in practice. Granted, my experience in the industries is currently only what I learned during my studies and 2 internships.
In general, C is supported. C++ is sometimes supported and very few people even talk about Rust.
Rust is more of a C++ replacement, no? Rather go with Odin or Zig or C3 for systemic stuff.
It’s fast and memory secure, so it’s good for stuff you might do in C but you don’t want to risk a memory leak or segmentation fault.
I thought more in the way of atomic dependencies and how it handles features in-language vs. in-code and reliance on toolchain vs. standalone. In short, how you as a programmer are supposed to use it.
It’s not widely used. Some car manufacturers(Toyota if I remember correctly) have started testing it. Some parts are really nice.
There is exactly one hal for i2c, spi and Io pins. As long as both your chip and peripheral driver implement against it, it just works. There are more unified abstractions in the work for things like DMA, but they are not officially stable yet.
Cooperative Multi threading can easily be integrated thanks to Async rust and executors like embassy.
All the crates that are no_std compatible can be included.
It’s not perfect, but it’s getting there.
