I consider myself senior engineer. When talking with junior colleagues they often are surprised how little I care about some things and how much I care about others.
These internal "attention weights" are highly influential parameters of how I work with LLM.
E.g. when working with Rust I often hold strict control over structures and lifetimes. But when lately I've been doing token-based bind generation I didn't care about anything outside of high level patterns like RAII and ultimately - API ergonomics which was verified in consumer app.
I've been in position of porting real-code to vibe-code platform and seeing non-technical people prompt-stream (they were shared across accounts) I know why they engaged engineer to run this work.
Their efforts took 6 weeks, I ported app within 4 days and (to be honest with myself) without LLM I that'd be 3M+ work pre-LLM.
In short: I observed same effect as claimed.
