I think the effect you're seeing is that different people have different levels of "good enough", and also they work in different domains where AI became good enough at different times. E.g. for one-off web page design it's been good enough for a long time.

I never said this for earlier models, because they did suck for things like Rust and SystemVerilog. Now they don't.

I'd share some things I've vibe coded that work basically perfectly but they're linked to me real name, but you could have a look at the Mold linker which was recently vibe-ported to Rust.
