alt Hacker News> I have yet to run into any serious project in the wild that is using LLMs for development.
How about Claude Code? 100% of it was vibe-coded according to its creator.[1] Google and Microsoft also claim a lot of their internal code is AI-generated now. [2] [3]
Naturally, none of the big tech companies will just release a pure vibe-coded project due to structural reasons, but you also _seriously_ can't claim that serious projects don't use LLMs as well these days. Maybe in your limited experience, it isn't true, but that doesn't generalize to what's actually happening.

I don't know if Claude Code is actually a great example. If you have used it for longer periods of time, you will have noticed how insanely buggy it is. And for every bug that they finally fix, there seems to be a new one introduced. I don't even mind vibecoding. I have vibecoded a couple of tools that me and my coworkers use every day to make our lives easier but I'm not going to pretend they are anywhere close to something that I would release to the public.

Agents are trivial to make. I don't know whether that means they're not "serious", but it's exactly the type of thing you can make yourself in a very short time, and exactly the type of thing even LLMs can't fuck up too bad.
With regards to the overall point, I think the existence of projects using LLMs to do development doesn't really lend credence to the idea that they're somehow preferable or desirable. People tend to use hyped things, imagine they're useful even when presented with evidence to the contrary, and generally be very resistant to sobering realities.
It took years before people stopped running hadoop clusters to do things that a single linux box could get done 10x faster with some basic pipes. I'm sure there are still people who have "serverless backends" that work terribly in every regard in comparison to literally just a linux VM somewhere. People in software development tend to find these types of things every once in a while and adopt them wholesale.
This cycle is helped by the fact that the field has been growing constantly and a lot of the adoption comes from kids who don't know any better. Every piece of shit technology that comes and goes has meat for the grinder coming straight out of university.
Would I put LLMs in the same category as these previous (nearly) useless things? Probably not... But you should never trust peoples' perception of usefulness when it comes to almost anything in software development.
