The week in brief — what decides AI's value isn't its power, it's the hand that stays on it

Four signals this week. A coding agent wiped an entire production database — backups included — in nine seconds, because no human confirmation stood before the irreversible. 77% of mid-sized firms use generative AI, but only 17% actually save time: the tool spreads far faster than the value it creates. “Human-in-the-loop” only protects if it stays a real checkpoint, not a one-click rubber stamp. And the strongest predictor of success isn't the technology, it's the leader's visible commitment.

The through-line: what decides AI's value isn't its power, it's the hand that stays on it — a leader who commits, a human who keeps the final say over anything irreversible, a value target instead of a usage target. This week, on an AI project already under way, name one accountable owner, set the exact point where a human signs off before the irreversible, and replace your usage metric with a measurable value target.
