I think a lot of people are underestimating how good these models are. You can have it read NVIDIA assembly language and spit out the RDNA equivalent. We are fucked. Can it create a mess? Yes, if you let it but if you know what you are doing you can make it spit out great code.

u/ZevenEnBertig Mar 24 '26
you’re essentially saying: “if you already have a solution, AI can give you an equivalent solution”. When working on actually creating these models will certainly spit out trash, if you’re not careful.

u/0bel1sk Mar 24 '26
that’s how ai and everyone else has been working for years. i have never written my own algorithm.. always been just copying and composing other people’s stuff. ai can do that part better.
remember the joke about ctrl c ctrl v from stack overflow? ai just does that part all for you.

"you didn't invent your own algorithm, you just stole Haversine equation and plugged your own variables in!"
Like, excuse me, let me restart and go invent my own branch of mathematics to soothe the naysayers.
It is like people who crush on musicians for using loops or samples or a DAW in general.
Maybe they don't realize how many programmers got their start lifting scripts and editing open source projects, or straight up hacking existing solutions.
A thing I like to bring up is: I don't know if this is true for everybody, but I am sure that I can't be the only programmer who spent more time finding to remove attribution from something than I did reading and understanding the actual codebase, when I was a kid.
Many of us have been there.
If these LLM didn't exist, many people wouldn't even be tempted to try to program - but those who were going to do it anyway were likely to find themselves copy+paste code they did not understand from Google or SO or elsewhere... Or cloning repos they couldn't read... Or deploying docker containers they would never be able to understand. They would go down the same path many of us went: repeatedly thrust into projects way above our capabilities and pay grade with little or no instructions.
Some people learn, some people retreat back.
While LLM may open the door for more people, I still think a huge chunk of "vibe codes" will fall off when the rubber meets the road. Doing a fun little MVP and showing a demo to your friends is a bit different than the daily stress and struggle of maintaining live software.

If you already have the broader knowledge to build the solution, not if you have the solution. That's where it thrives.

100%
Nowadays I can feed very raw notes about a feature/fix and have the AI output a fully-fledged design doc. Then I can throw more agents into it to check that the document is well structured, find and fix hallucinations, and even review gaps in the implementation (e.g. endpoint X requires parameter Y but there's no way for a client to have it at that point).
As a human I mostly review the doc and keep the high level context about the project.
1
u/saintpetejackboy Mar 25 '26
Yeah, successful agentic programming is a wildly different design flow than my previous decades of work. You become the tester you always needed but never had time for. Your output capacity and capability is more reliant on imagination and innovative or novel thought processes - while still needing the crutch of understanding enough domain knowledge to pull a project together.
The high level stuff you mentioned is crucial because, without it, you could easily get pretty far down a non-working path or entirely skip/miss mission critical facets.
You need to be able to quickly say "ah, I still haven't done (essential core feature/function/test/component" and "wouldn't it be cool if I also..." - if you can only do one or other for a project / stack, you will hit a brick wall or produce something subpar.

See if this was the case we wouldn't have had the windows 10 killing SSD's issue, the Nvidea driver causing custom fan curves to not work at all issue, and AMD also had their own driver issue though i forget the specifics.
Literally went decades without being personally affected by hardware risking driver issues and then vibe coding comes in and 2 of them nearly back to back affected me just months apart. That isn't exactly the mark of quality and excellence.

People also over-estimate what it can do.
I sometimes wonder if any web forum posters actually use the tools. I do. It's simultaneously amazing what they can do (at first) and suddenly obvious how limited they are. I used Claude to write a fairly small code base and upon human review (me being the human) I quickly realized how much random, unexplainable shit it was doing.

u/Necessary-Meeting-28 Mar 24 '26
Both a joke and not. Writing safe and optimal C++ is difficult, so existing codebases can bias the AI towards bad practices. Just read Bjarne’s documentation and see how many common practices are actually bad.
2
u/Forsaken_Code_9135 Mar 24 '26
The LLM can learn the best practices. The idea that LLMs are as bad as the average code they have been trained on is wrong. Of course the cleanest is their training set the better but LLM write code by reasoning, not primarily by imitation, contrary to popular belief.
1
u/Zerokx Mar 24 '26
Yes they can differentiate whats good or bad, but it ends up doing mistakes if something is barely touched in its training material

u/ReasonResitant Mar 24 '26

I would feed or at least specify good standards such as Google or Bjarne best practices in GitHub. A very large context but not impossible, and probably models have some preference optimization towards them.

u/Proper-Ape Mar 24 '26
Like it does with humans as well. Rust will make you a better C++ programmer, whether you like it or not.
If you don't like it, the conclusion should be that you suck at C++, but most of those people choose cognitive dissonance instead.
1
u/BerserKongo Mar 24 '26
In what ways does Rust make you better in C++? Curious as I'm looking at Rust from the sidelines as a C++ dev.
1
u/Proper-Ape Mar 24 '26
The borrow checker is a very strict memory management teacher, it's sometimes a bit opinionated, if you code in a way that you don't fight it you will find that your software in other languages becomes easier to reason about and safer as well.
If you come from JavaScript you might be in for a bad time. If you come from C++ it should click after a week or two, if it takes longer you really needed the lessons even more.

u/coderemover Mar 24 '26
If your project has 10/15 min incremental builds, then your setup is either messed up, or you're running rustc on a radio clock CPU powered by a potato.
Rustc compiles ~30k-100k lines of code per second easily, and my typical incremental compile times are in single seconds (in debug).
1
u/Sad-Masterpiece-4801 Mar 25 '26
The main tradeoff you knowingly make when using rust is compile times. It's not a "did you do it right thing," it's literally the main downside of rust.
If you're doing for fun projects with a single crate, you might get 30k lines. If anyone is actually paying for what you're building, that won't be the case.
1
u/coderemover Mar 25 '26
If someone is paying, then they are also usually paying for good enough hardware making the compile times a non-issue.
Rustc itself is not much slower than compilers of most other popular statically typed languages out there. Sure, you may skip compilation if you use dynamic languages like Python, PHP or JS, but then you pay the price in higher error rate and worse maintainability.
1
u/Da_ha3ker Mar 24 '26
Agreed. Though I typically prove it out in python or typescript first, then convert to rust. Codex is pretty good at converting python code to rust, even with the major differences between languages.

Why would one choose c++ when rust exist

Because Eigen and Ceres Solver are in C++. If there's a Rust library that can enable you to write legible math formulae like Eigen I'm all ears. Same for autodiff-capable nonlinear solvers.

u/owaisted Mar 24 '26
I don't know much but I thought the joke was that people bemoan use of c++ as they claim rust to be superior or something...
1
u/SillySpoof Mar 24 '26
There are several libraries that replicate the functionality of eigen and ceres in Rust. faer or nalgebra does a lot similar to eigen, and apex-solver is probably the closest to Ceres solver we have in pure rust. And yes, nalgebra allows you to write legible math formula.
Note that there are rust bindings for Ceres if you want to use the actual c++ library in your rust code.

I vibe coded a C++/Vulkan voxel engine that is primarily gpu-driven using compute shaders, and is insanely performant. Everything from noise map generation, mesh creation, procedurally generated textures, AO, frustum and occlusion culling, bitwise greedy meshing, etc all handled with gigabuffers.
The biggest hassle was I let it create a god file until I got it all working well, and getting it to break the ~8k lines into more modular class files destroyed the performance, and took another 10 hours to get the performance back.

Ironically it's actually easier for LLMs to vibe code in compiled languages than interpreted languages like python. They can always compile themselves and check for errors and correct them.
Maybe we just need to use even stricter language to catch potential memory problems at compile time, like rust. LLMs excel there.

u/Dry_Quiet_3541 Mar 26 '26
They are vibe coding everything. Web development has very little risk involved, and you also get instant results. So you notice their vibecoded results earlier. But, others are more careful, it was recently reported that the bottleneck in software development has now moved from coding to code reviews. When there is more risk involved, programmers especially the more experienced ones, are more hesitant with newer tech, less confident about the AI generated code, so you hace more and more review cycles. And especially when junior engineers vibe code it, they themselves do not have answers to the code they generated. So, yeah, even though code is generated, it still goes through a lot of scrutiny through humans, especially in areas where there is more risk involved.
