alt Hacker News> Epic may have “vibe coded” a faster client, but Valve proved that targeted optimization on a decades-old ecosystem can still beat out AI speedruns.
Optimizing a project with AI is one of the most trivial things you can do with AI.
I also wouldn't buy it for a second that Valve engineers aren't using AI, especially for something as trivial as "hey claude rank the top causes of slow startup" -> "oh okay now fix". The most I'd grant is that everyone uses AI secretly as a sort of dark forest problem.
Once I had a good benchmark script, Opus 4.8 or whatever made my terminal app faster with less memory than ghostty and kitty. It's not even interesting.

The dark forest hypothesis is that we can't find any alien life because it's dangerous to broadcast your existence and location to competitors. So rational thing for every alien civilian to do (and arguably for us) is to keep quiet.
But what does it mean in this context?
Yeah exactly, Valve engineers probably just told AI to make it faster.
Your "dark forest" analogy sounds reasonable but Epic's outright admission of "vibe coding" is a bit of a footgun considering how rabidly anti-AI the folks on sites like Reddit are. If they had just been like, "it's faster and supports Linux" they would be the darling of the internet.

I don't see why not. They clearly know what they are doing at Valve, and for an engineer who knows what he's doing, LLMs are of very limited use.

This is probably the saddest comment I've read on HN. It really shows the state of this place and how far into psychosis the comments have fallen.
