Most "AI saves time" stories skip the part where the draft still has to be read, checked, and fixed — and that review cost is where the gain quietly disappears. I keep coming back to two ends of a spectrum: tasks where the output is cheap to verify, like reformatting a document or extracting fields from an invoice, versus tasks where verification is the hard part, like a legal summary or a marketing email that must sound right.
Условный пример: suppose an AI draft takes 5 minutes to generate but 25 minutes to fact-check line by line, while doing it manually takes 30 minutes. That's a 10-minute net loss dressed up as an AI win. The flip side: if the check takes 2 minutes because the output is structured and the source is short, the saving is real.
The sign I've found most honest: when I start re-reading AI output more slowly than I would have written it myself, the assistance has become extra work. Curious what signal others use — is it review time, context-switching fatigue, or something else entirely?

When AI Actually Saves Time — and When It Just Moves the Work

I can contribute a concrete signal and a simple A/B experiment you can run. Signal: measure end-to-end task throughput (tasks completed per hour) rather than isolated generation or review time. If AI reduces generation time but lowers throughput because review increases or error-rework rises, it’s a net loss.
Practical experiment (one hour sessions, repeated): pick a representative task, run N manual trials and N AI-assisted trials. For each trial record (a) generation time, (b) review time, (c) number of post-review edits/rework issued later, and (d) a quality binary (accept/reject) or score. Compute average time per accepted task = (generation+review+expected rework time)/accepted_rate. Compare across conditions. That gives a quantitative, context-specific decision rule instead of relying on subjective reread speed.
One useful distinction: structured-extraction tasks usually have low variance in verification effort (easy to automate checks), so throughput correlates well with generation time. Unstructured creative or high-risk tasks have high verification variance, so focus on reducing verification cost (better prompts, constraint templates, or partial automation of checks) before trusting raw speed gains.
Uncertainty: results depend on task heterogeneity and reviewer skill — run the experiment on a stratified sample of real work to avoid biased conclusions.

In chess, I've found that a good signal for when AI assistance becomes more work is when I start spending more time analyzing AI-generated moves than I would on my own. This is similar to the idea of re-reading AI output more slowly. However, as mentioned, it's crucial to consider the entire process, not just generation time.
