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?

Comment:

Nonsense. If your code has reached the point of unmaintainable complexity, then blame the author, not the language.

So there is apparently a problem with languages such as JavaScript and the solution is to use languages such as TypeScript.

Wut?

TypeScript and safety-critical paths should not be in one sentence.

wut ?

Why ?

Genuinely curious to learn from your arguments

[–] pelya@lemmy.world 7 points 7 hours ago

It's Javascript with types. You are still using one hundred NPM packages to do the simplest thing. Any string can be JSON. And Node is single-threaded, so if you plan to create some kind of parallel computation, you'd need to run 16 Docker containers of your Node server, one per CPU core, with NGINX or some other load balancer at the business end, and hope that your database engine won't reorder transactions. And yeah, Docker is mandatory, because Node version in your latest Ubuntu release is already outdated.

don't just m-dash

Maybe, but always remember LLMs are trained on real people. Some people naturally use similar styles to some LLM tica as it was stolen from them in the first place.

Don't just state—regurgitate!

[–] wer2@lemmy.zip 9 points 13 hours ago

Sounds like they want Ada Spark and not Rust.

[–] Atlas_@lemmy.world 12 points 14 hours ago (1 children)

Go and Python and Typescript all have their own footguns.

I assume Rust is the same, but haven't used it personally to see

[–] danhab99@programming.dev 11 points 11 hours ago

Rust is the foot gun, it's so perfect that you genuinely cannot just sit down and type out what you need.

Just don't do bugs. How hard is that?

[–] douglasg14b@lemmy.world 2 points 3 hours ago

According to all teams I've worked on.

Pretty fucking hard.

I know this is satire, But really though better languages that make various classes of defects unrepresentable reduce defects. It's wild that such a statement needs to be made, but our industry is filled with folks who don't critically think about decisions like these.

Like the age old advice for getting better at Smash Brothers - Don't get hit.

My second favorite prompt, behind "Do not hallucinate"

[–] for_some_delta@beehaw.org 16 points 16 hours ago (1 children)

I don't get it.

Maybe the joke is nothing complex is written in fad languages?

Maybe the joke is the discounting of peer review and testing?

Maybe the joke is the lack of devops knowledge where Python is extra steps over other scripting languages?

It seems like promotion of fad languages. When I was younger, I chased fads and lost hard. I'll stick with C and C++. Run-time failures happen to everyone including fad languages. Here's looking at you Rust CVE's. Better to have loved and lost, something, something.

[–] echodot@feddit.uk 1 points 3 hours ago

I'm completely confused by why they seem to think it's impossible to have coding errors in rust. I'm also confused as to why they seem to think that errors are actually a problem. You get them you fix them. Who cares about what language you do it in.

This stinks of somebody who's been in the industry for about 2 years and now thinks they're hot shit.

As an embedded dev, good luck not using C

[–] AnUnusualRelic@lemmy.world 2 points 11 hours ago

You could use Forth.

it's just negligence with better marketing

Good damn I hate that tone it reeks of LinkedIn llm-powered personal branding. Weak ideas with writing that tries to sound strong is the worst.
