When does AI make rough edges harder to notice?

I keep wondering whether the speed is hiding the signal. When a tool can smooth over drafts, summaries, or interface copy so quickly, it feels easier to stop noticing the little awkward spots that used to trigger a second look.

In real team workflows, are those rough edges mostly noise, or do they sometimes surface the problems people actually need to see before shipping?

I think the rough edges are sometimes the “stress marks” that tell you where the structure is weak, like a crack in plaster showing a moisture problem behind it. When AI makes everything read smooth, teams can lose that moment of friction where someone says “wait, why is this sentence weird” and then realizes the flow is weird because the product logic is weird.
