Practical AI for Work Efficiency

The 60-second version

• Google Cloud announced the Gemini agent on Oct 8, 2026, saying it can split business tasks among sub-agents that run for hours or days and that each coworker agent gets its own email account and audit trail.
• A preprint by Hongzhan Lin and five co-authors, not yet peer-reviewed, tested ten model-and-app setups on 656 cases; in three setups re-checked on the same 100 cases, judging accuracy was 95% to 99% but success at doing the work was at most 52%.
• Franz Enzenhofer's open-source Mac tool Big Arrow on the Screen, whose Show HN post had 368 points and 161 comments on Hacker News as of Oct 10, lets AI agents draw arrows and signs on screen but never click, leaving the action to the user.
