arXiv:2610.35942v1 Announce Type: new Abstract: I consider what it means for AI assistance to save time. I contrast a stopwatch view, on which time saved is whatever the clock records, with a ledger view, on which it is a counterfactual that has to be read next to the errors the work lets through, and I argue for the latter. The argument has four parts. I define a model-free pair of quantities, ti

So what

What this event means by reading role—not a longer recap.

BuilderIf you ship AI drafting tools, track escaped-defect rates alongside clock time, since over-trust can buy minutes at a larger total cost.
ResearcherOffers a model-free time-saved/excess-defect framework and a replication showing METR's slowdown estimate ranges 19-24% by estimand.
