> 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.
